I dunno, it's pretty weird how MLP blew up...I've seen at least, like, five forums where either...
A) Everyone is into MLP. One forum I visit pretty much has all the mods in on it, and the other day someone literally steal-edited a person's post in a quote and changed "somebody" to "somepony". It really freaked me out, because the topic had nothing to do with MLP and it was never mentioned, but someone decided to edit a post to include it. :/
B) MLP discussion is literally banned. I know it's like this on SA, and I recall for awhile GAF had a lot of anti-MLP sentiment after it began to leak into every thread.
So I can understand why people are weirded out.
The part that bothers me the most, however, is how people act like MLP is the first show made for kids that teaches life lessons...when most of the life lessons are stuff most kids learn, or should know, already at a young age. This is pretty much on display in that infamous "Brony Sociology Chart" and the equally infamous picture of the Holocaust with the pony inserted in, where one of the comments literally has a person stating that before the pony wad added, they weren't able to fully appreciate the horror of the Nazi regime. :/
