Originally wasn't going to bother posting in this thread but changed my mind.
People can like whatever they want. I don't care. The problem I have with My Little Pony and "bronies" is that they're loud. They don't just love the show, they turn everything into a conversation about the show, constantly asserting that they're masculine because they don't care what people think of them. That is what annoys me, and in turn I've grown to hate the show.
I watched an episode to see what the big deal was about a year ago. It was terrible. It's not even something like Spongebob where it's a kids show that you can find entertaining. It was actually painful to watch. It doesn't have a rich plot or amazing characters or whatever the hell else bronies claim about the show - it was designed for five-year-old girls, which is exactly why it is as intellectually unstimulating as it is.
