XD You just... You kinda feel it. You have that wish to be more than you are... It's really for me a matter of feeling free because when you're behind your fursona it's like your life is perfect. It's like the ultimate safety and acceptance. I've never heard of a homophobic or racist furry ya know? It's by far the most accepting, crazy, fun community. The best way to know is to look through the fan base and see if anything in particular interests you such as Art, Fursuits, acting like an animal, Dancing, and many other aspects of the community (That's some of the more light-hearted fun things)
