Because I'm one and I just want to know how many other people out there abandoned interest in that show.
I dated a bronie once. Now he's my ex. So technically he's an ex bronie. (that's not even a joke though it actually happened)
Most of the bronies I know that are still here make no indication of it now. The other veterans who were bronies have disappeared off the face of JH. from what I gathered, they are male MLP fans.
