(I'm kinda new to the brony community, so correct me if I am wrong in any way or if you disagree.)
The brony community is somewhere where those that enjoy friendship (loyalty, honesty, ect.) can kick back, talk, and enjoy knowing that there are others like themselves. The brony community is, most likely, the most organized fan group in the world right now. It has poetry, stories, art, and, the one thing you can't forget, cool people. And because of this, I think the trolls and haters know our organization and see us as a threat. So, being the jerks they are, they need to break it up and ruin it all.
Summary: Bronies = Awesome people
MLP = Pure Art
Trolls and Haters = Cruel bastards that don't know what enjoyment is.
