I may be wrong in my judgements
The issue is that you're conflating "furry sexuality" with beastiality when they come from very different places with very different outcomes and moral implications.
The short story is that humans at ~10yrs old start learning and coding for what features they find sexually attractive which happens to co-incide with the target audience for many anthropomorphic films/cartoons/etc. and so some small percentage start developing an aesthetic and/or sexual preference for animorphism which then creates a subculture that feeds back onto itself.
It's not "beastiality" it's "mickey mouse-iality". It's not a sexual attraction to animals, it does not result in harm to animals, it does not result in rape or consent violations from those unable to give consent. It's as close to beastiality as anime girls are.
I'm going to get a lot of hate for this, but for the majority of furries, their fandom is at least party sexual in nature with over 70% of furries reporting they they view furry porn. Personally, I find that disgusting and I feel that the furry community's constant need for validation detracts from the seriousness of LGBT issues at large. I may be wrong in my judgements, but the claim that furries are just people with a hobby is an attempt to sweep an inconvenient truth under the rug.
