Furry being a fetish is just a myth
If you're talking about zoophilia, Only 0.02% of the ENTIRE fandom is into that
Other stereotypes like, All furries are gay, Want to be treated like animals, F**k eachother in fursuits, Are all myths.
The ACTUAL furry concept comes from the idea of a "Persona".
Persona is a some sort of public image you create to interact with others, But sometimes, You just wanna use your true and inner persona, So the people of the furry fandom, Create a new persona resembling an animal, With it, You no longer have to be shy to, Dance around, Draw, Sing and pretty much, Be yourself.
The only reason they look like animals is because, Well, Who doesn't like animals?
Also, Another stereotype, Only 40% of furries have fursuits.
