Ok, now, the reason I'm an extreme Brony is because:
I have posters
I listen to MLP songs all the time
I watched the movie 5 times
I read most of the MLP comics
I draw MLP comics
I'm currently working on a MLP animation
I think about it all the time (When it's appropriate)
I have a plush and treat it like it's my own child
I've been a fan of MLP since 2010 when the first episode came out
