I doubt most people know an open furry. But there's always been antifurry hate since they're kinda weird and niche and you can always try and link them to bestiality but just like now its always just been a thinly veiled wedge to start hating on gay and trans people and really anyone different. I think a lot more people understand intellectually someone who was born male but identifies as a woman than the whole fursona thing. Honestly antifurry rhetoric seems like an easy predictor to all kinds of minority hate. Love the litter box in the bathroom one have to tell people that's obviously stupid all the time.
