Normally, people being bronies doesn't bother me all that much, it's not something that should crop up on my radar, but when I see them posting ponies, pony anecdotes and other such things where it is absolutely irrelevant, off topic and uncalled for, then get all defensive when you call them out on it? That's when I get pissed off.
Yes, I fucking get it, you like the show, now would you kindly stop posting about it in every single god damn thread? (Not you specifically, more generally towards bronies who do this.)
Also, I god damn wish people would stop trying to get me to watch it. No, I have no interest in it, the premise does not appeal to me in any way whatsoever.
