Obnoxious liberals and conservatives reign in reddit. Liberals have specifically plagued paleontology and spec evo subreddits. Paleontology because they want to humanize and anthropomorphise Neanderthals and other extinct hominins, and in spec evo because they want to humanize animals, make inpossible creatures get accepted by science and claim that chimpanzees are sapient despite having the intelligence of a 3 year old. Showing they have a pro-xeno and anti common sense mentality.
