The only thing I will say about the whole bronies vs. MLP-haters thing:
If you like a show, fine. Post maybe one image every 2 weeks to non-fan-forums, so people aren't annoyed by the constant image macros. If people mention how much they hate your favorite show, politely disagree, then let the matter drop and go on with your life.
If you don't like a show, fine. Calmly state your dislike, and let the matter drop and go on with your life.
A TV show is not worth drama.
