Arguably.sorry user name taken. said:no but i have friends...that really really like sonic...
is that the same?
I had a friend in high school who loved the character knuckles. She got a red collar with a red name tag. She drew Sonic art constantly. I would say that she could have been classified as a furry, but really that is up to the person themselves.
If you tell a person that a furry is just someone who likes the art, and they go "oh, yeah, well, that's me then," then no biggie, easy classification.
All the same, as some have made apparent above - not everyone is comfortable with that group or its stigma.
