>>5266825For my understanding, they are annoying because they want to fuck animals with human features(i.e walks in two feet but still covered in furr) unlike other characters that are human with animal features(i.e girls with animal ears and tail) and will shove them to everyones faces even if they are not in websites like 4chan or a dedicated furry website
If you wanna know more, try searching in Youtube "Mister Metokur furry" he has good videos explaining why people don't like furries
