All my brony friends stopped liking the fandom and the show because of the 'haters' (usually a minority that take the show too seriously and spam hate comments everywhere, to the point where it feels like 80% of the comments are made by them).
I personally never cared about fandoms, but thanks to this type of stuff I have no1 in real life to talk to about the show.
It creates a ridiculous situation, where the show lose incredible amount of potential fans because of maybe 1% of the community.
