Funny you say that, because in the first paragraph of your post you're stating that, "The reason I hate MLP fandom is that it distracts me from more interesting portions of the internet". The minority of people who watch the show, and the fact MOST of it is contained in one large thread results in you almost never having to see/read any of it. Unless you frequently browse /b/ or ponychan, you won't have to worry.
I don't browse /b/, and I don't browse ponychan.
I browse YouTube. I go look up some anime/touhou videos that are unrelated to MLP, and guess what? Ponies.
I go on Google Image search to find an image that shouldn't have anything to do with MLP. Guess what comes up? Ponies.
Plus, I don't have to state again: avatars. Ponies.
Trust me, I'm not complaining just because I can. I'm complaining because of how far and out of control this has gotten. It'd be like if I went around spreading random anime images all over the place, changed my avatar to a new anime image every other day and all that. I don't do that because I try not to be annoying, and even give the option for people to use Adblock to make my avatar not show up for them if they don't want to see it. When basically anybody who watches MLP figures out that one person's blocking their avatar using Adblock, they flip out and rage over something so stupid, then try and change it every 5 minutes so that it shows up. I admitted in the last thread like this that I block MLP avatars from showing up on my PC, and about a month ago, I cleaned out my Adblock filter. Within a month, I've managed to block a whopping
106 MLP avatars, seriously.

One hundred and six. This number will most likely rise today by at least 3-4, if not more.
Like I said, I have friends who are into MLP and I'm fine with that because they aren't annoying like almost 90% of the people on this forum who's into it that are running around with avatars and all that. I'm also assuming you're into it, but I don't see you randomly spreading it around, and I respect you for that. You're on my good side for that.
This calculation excluded all posts in the pony thread because the pony thread was deliberately created to appease the anger of people like you.
But saying that the MLP thread was created to anger others who hate it, you're saying that everybody who watches MLP and posts about it/is just a fan of it does so just to piss everybody off. Therefore, you're basically saying that they do it just to troll and try and be cool. That's what I got out of that part of your post.
I don't hate MLP without a reason.
