Is it any wonder that the years in which people stopped translating proper nouns, the gulags and world wars and the spread of creationism happened?
Before the 1900s, it was not unusual to hear of "Nicolli Niccolobi" by Cesaro Dickensi. Operas were translated into the language of the host country. Once that stopped happening, genocides started happening, as they should have.
f*ck the 20th century, right in the ass.
