And here's reason one on display: furries will insert themselves into a community, post their furry art, act out with general furry degeneracy, and when you point it out and tell them to knock it off, they will immediately play the victim card and act like they're some sort of protected minority that's being executed en masse IRL.
To put it nicely: you people are weird, you know that you're weird, and instead of accepting it and keeping it to yourselves you feel the need to push your fetish onto the general populace of other communities.
