The idiocy doesn't prevent bronies from calling themselves bronies. Seriously, learn more about us before you call us weirdos in a basement.
If you like watching a show that's one thing.
If you like watching a show and then call yourself a brony, what does that say? It really shows how far you are willing to take a show.
This is about as bad as when everycigarette started calling themselves an emo.
Just be yourself, don't label yourself.
