So...
I don't know whether these guys are furries or not, i'm not too sure on the definition, but anyone who's into bestiality is definitely low on my "I want to converse with" list. I see furries as a way to justify wanting to perform bestiality, similarly to how people who say getting off over lolicon doesn't make them a paedofile because "it's not actually real".
Not saying all furries want to perform bestiality, similarly not all people who are into bestiality are furries. There just appears to be a large crossover from what I see.
