honestly furries are fine until they start getting cringey. my scale is this:
0 - not furry.
1 - just wears costume and makes art - completely fine, I treat them normally
2 - says uwu owo etc and does cringe - kinda annoying, just ignore them
3 - unhealthy obsession - ignore them, but try to tell them why not to get obsessed with that stuff
4 - yiff watchers etc - oh no. make them stop.
5 - zoophiles who actually try to f**k animals - arrest them
