All I see is a serious lack of understanding. Oh well, haters gonna hate. I mean that's really all there is to it. People can say whatever they want on the internet, but most of them are too scared to say that stuff to real life bronies. I don't know about you guys, but the only negative responses I get when being an open brony is people staring at me, then I stare at them, and then they look away.
... Wow, I'm still a strong Christian who watches MLP. lol And the part about RD's tail meaning the Homosexual flag was hilariously ignorant.
Trolling is not hating. Trolling requires a completely unbiased viewpoint. Here we can tell that this is trolling because both sides are insulted by this.
On the subject of Christians, I am one as well (Catholic) and I watch all the science shows, MLP:FIM, American Dad, Family Guy, and much much more that people like that wouldn't like.
