For example, I believe that all, non-human yet living entities are people, and thus should have property rights over themselves. In order to disprove this argument, you need to provide (for example) a relevant difference which makes adult chimpanzees/bacteria/plant matter incapable of having property rights over themselves but human babies capable of having property rights over themselves.
"Person," ethically or legally, does not mean "human." It is a distinct word for a reason, because it expresses a different concept. (For example, corporations are persons from the perspective of being able to have legal rights.) That is why this is no mere "game of semantics." Personhood, as generally understood, is understood as an entity which we consider to be a self and which is capable of having rights accorded to it. This is not a definition I made it up; it is the commonly accepted definition of a person from the socoiological or moral perspective.

The group of beings that are considered people has generally grown throughout cultural time. It started off including only male humans, then expanded to include female humans, racial minorities, etc. in most countries. So while in common parlance person is often used interchangeably with human, it has a distinct usage in morality and that is the term I am using.
So this is all important because the set of beings that we define as "persons" are really just those capable of having rights. (We can use that longer terminology if you want to avoid the person/human debate, but "person" is more succinct.) Now, you're accusing me of a game of semantics because my group of "persons" includes non-human animals and yours does not, and you believe there is no way to resolve this. However, the argument I am making is that if we are to have a group that we are defining as beings capable of having rights, there has to be some set of meaningful qualities that these beings have, which sets them apart uniquely as persons. My contention is that there is no way to construct a set that includes all humans but excludes non-human animals, without explicitly relying on some arbitrary category boundary like "species" or "race" or "gender" which we can hopefully agree is not a morally relevant characteristic in itself. That is why I don't need to know what your specific set is; it is sufficient to point out that if you try to set it up in this way, you will fail, because any quality you choose will be present in some non-human animals to a greater extent than some human animals. If you do not believe me, define your personhood category and we will discuss it.
To what degree are all non-humans similar to all/nearly all humans? There's still the role of consent and communication (e.g. preference revelation), which you neglected.
I did not neglect this, you neglected my response to it. As I observed, the ability to consent or communicate in spoken language is not a prerequisite for the ability to have legal rights. Human babies are recipients of some baseline legal rights protections, including the right not to be killed, despite not being able to consent or communicate in a way more meaningful to us than a cow, chicken or pig.
(Edit: I see now that you included a response to the issue of children. Even if parents have
de facto ownership of their kids, that does not mean that children are incapable of having certain rights. In our society children always have the right not to be imprisoned (at least by people other than their parents) or to be killed, regardless of their age. Even though the bundle of rights and responsibilities increases over time, they always have some and are always
capable of having some. A child's parents cannot legally or ethically murder the child.)
There's also the persistent failure of the vegan crowd to control for their anthropomorphic personification of non-humans
This is not a serious failing of the "vegan crowd." The implication of your statement is that it is possible to empathize with and understand the experiences of other humans, but not with non-humans. But how do you know, when you are conversing with someone, what they are really feeling? You have never been them, or been able to feel their feelings. They could be lying to you; they could be a sociopath who interprets stimuli completely differently from you. The only way you can really be confident that they are likely to be capable of feeling similar things to you (and thus as deserving of moral respect as you do) is your trust that because they are biologically similar to you, they likely experience the world in roughly the same way. If we go this route, we have no choice but to respect the sentience of non-humans. From the perspective of evolution and neurobiology, we have discovered no reason to believe that non-human animals respond to stimuli like pain and pleasure in fundamentally different ways than we do. Most parts of the human brain map onto the brains of other mammals. This has to be so, evolutionarily speaking; what makes us different from other species such as chimpanzees is merely the size and complexity of a certain part of our brain, there is nothing fundamentally unique about the human brain from a biological point of view. As an example of the difficulty of the speciesist position, imagine if we discovered a relict population of Neanderthals on a remote desert island. How would these people fit into our current legal hierachy? Would they be considered persons? That there is not a continuum of extant beings in the mammals is an accident of history, not a statement about morality.
Were there not black men who were free? It's not like that white crowd would call a freed black man property of another human.
True, but some black men were property, and whether or not a black man was free was often dependent on accidents outside their control like their birthplace or whether they spent time in a free state. And that particular bit was fairly unique to the US, you would not have had such a chance at being free in the older societies.
Even before the slave trade during white colonialism, there was enslavement among all sorts of tribes across the world. Before that, it was more efficient to destroy people (e.g. human sacrifices). After some time, captured humans became more valuable as slaves instead of dead bodies. Why? The production possibility frontier expanded due to changes in technology. The marginal productivity of humans increased, so keeping them alive was more valuable than killing them all. Over time, people began to realize that the old form (slavery) was less productive than granting people freedom over themselves. This transformation is partly explained by evolving moral arguments but its also explained by the realization of greater gains from trade. Being free results in good incentives to be more productive. Hiring people instead of enslaving them tends to be less costly. Self-interest becomes gradually more aligned with social interest as property rights over humans becomes more respected.
Again, the benefits, costs, and constraints played a role in this evolution of the concept of "human" and "freedom."
So we can agree that if you were alive in 1857, you would not have fought for abolitionism of slavery because you thought white people should be able to decide for themselves whether the costs of allowing black humans to be free were justified?
Well, I've easily exposed the ridiculousness of your analogy--given my axiom of maximizing human welfare through recognition of property rights for humans over themselves.
Your analogy is useless in the current discussion because it starts from the assumption that human welfare is worth maximizing. We are currently debating what organisms belong in the group of beings whose welfare should be maximized, and if I am victorious in convincing you that some non-humans should be considered moral persons if humans are too, then it becomes important to maximize the welfare of the group of humans + some non-humans. If on the other hand you are victorious and win the point that non-human animals are not persons and therefore their interests are not worth considering in welfare maximization, then your point will be valid -- we can do whatever want to non-human animals, because it is only the interests of humans that matter. So I am not debating you on that point; under your category it is correct, but it is the category we are debating.
Currently, my reductio ad absurdum holds, and the many problems (i.e. incoherence) of positing that animals have equal human rights
I did not argue for animals having equal rights to humans, so your argument is nothing more than a straw man. The current debate is whether animals are even
capable of having legal rights. It is only once we have agreed upon that, that we can start discussing which specific legal rights animals should have.
