I used to watch the show but stopped. Not because I didn't like it anymore... Just don't watch it anymore. Have way too much stuff to do and it isn't important in terms of shows I enjoy watching.
The fandom was a bit too much for me as well. There's always a vocal minority within a hobby that gives it a bad rep, but there were a lot of people that just turned me off from it. Like I met people that were crazy obsessed with it(but I have with literally like every hobby, so it's a bit irrelevant). They really gave the fandom a bad name and didn't want to associate with it as much anymore. Each hobby/fandom always has people that give it a bad rep, but MLP really, really got the worst of it, as in it's gotten a lot of hate more so than usual, sadly. I have best friends who love the show and are not the vocal minority, but even if they were.. That wouldn't change anything as I already know them.
Don't get me wrong though, I think the show is good and will always and have always defended bronies, but I just don't associate with it anymore because I "grew out of it" so to speak.
Anyways, my favorite character was and always will be Twilight.
