Edit: As people in the comments pointed out, this bill targets all websites hosting porn. e621 just happens to be hosted in Arizona, and it therefore affects them directly.
Not really. It’s people who enjoy art of personified/anthropomorphized animals. Sometimes it’s sexual, sometimes it involves personas and costumes, sometimes it’s just rabbits in bankers’ outfits. It’s viewed as weird by a lot of people because they assume it’s all costumes and sex, but looney tunes technically also counts, so it’s much more widespread than people identifying with it is.
There's almost certainly way more zoophiles among the furry population, but most(?) furries aren't attracted to literal animals AFAIK. Or don't act on it. Uh
