Ummm...I'm sorry. But Bronies couldn't possibly be creepier. That show is like a pedophile recruiting video.
No.
That show is a children's cartoon, but, as with lots of things, others outside the 'target audience' are also entertained/enjoy the show.
Eg. I am 58 and have 4 tattoos....one I drew [see my avatar] but the others are cartoon characters....Marvin, Taz, and Wile E.
There's nothing particularly weird about that....
