Not a furry, but I do have a TF fetish. Using furry websites exposed me to the good and bad sides of furries and ultimately has, I believe, led me to more critically think about the nature of online rhetoric when it comes to repressed identities and over-expressed identities.
I'm given to believe that a big draw of fursuiting, for example, is that they can be whoever they want in public. They can bear the whips and arrows of scorn because they're in a silly badger costume and don't give a single fuck about anyone else's opinion about what they do with their time and money and bodies legally in public.
I wouldn't be surprised if there isn't some kernel of resentment against the ability to be who you want to be without fear of societal pressure that can cause a kind of overcorrection on other end that just pushes people into blind rage.

Why should they be allowed to do this?" Now [they were] sobbing. "I can't!"
