Oh, you're one of those who think being a brony is just a fad, how cute.
By the way, this is a pony forum. The name of this subforum is "My Little Pony". Coming in here and bashing bronies is like coming into this forum as a whole and bashing people who like tf2.
Isn't it a fad though? My Little Pony and being a Brony got very popular in a relatively short amount of time and thus, like a fad, will be forgotten just as fast. That's generally how fads work (ie: Pokemon, Inu-Yasha, Avatar: The Last Airbender, Yu-gi-oh etc). You can also call it an "internet phenomenon" due to the fact that because of the internet, it gained popularity from males ages 15-35 and MLP was able to spread quickly via videos on youtube and/or forums. To think that the popularity MLP is going to last "forever" is somewhat shortsighted and childish, honestly. It doesn't have the ablity to become a cultural phenomenon either, due to the limited range of it's target audience and the general negative stigma that comes with watching what adults think as "children's shows". Especially since it's aimed at little girls, making even more difficult to have a cultural impact.
Lets be real here, MLP is no Simpsons, Micky Mouse or Tom & Jerry. It's based off of a 1980's pony toy line for young girls. Believe me, as a girl, no one remembers little girl's shows, like Jem; it's always boy's shows like Transformers that retain their popularity. I don't know why, I'm assuming it's our masculine culture that denounces femininity as being weak, but that's a whole other sexist hot mess. Shows like this happen all the time; MLP is just flavor of the month. Even if there's MLP conventions, the popularity of being a Brony will not stay at it's peak. So, no, it's not "how cute", it's what's actually going to happen. It might take a while, and it even might be popular for another year or two, but eventually it's novelty will wear off, you'll find something else and it will be forgotten. I mean, come on now. No one plays Yu-gi-oh cards anymore. And Yu-gi-oh was even more popular and mainstream than My Little pony is.
On the note of forums, Skial is not a MLP form. Ponychan is strictly a pony forum; everything on that forum is dedicated to ponies and pony related material. If you want a place to freely discuss MLP without being harassed, that would be the place to go. This is a subforum of Skial. This was created because people were tired of pony shit-posting on threads not related to MLP. Why do you think /mlp/ was made on 4chan? Same reason. People got tired of all the pony posts on /b/, so mods had to create a place where most of the fan's energy could be channeled in another place. It's true that it's not fair that we come here and make fun of you guys for liking MLP, but there still is pony shit-posting on other parts of Skial, so just staying on this subforum doesn't make you immune from criticism. It's "an eye for an eye" type of mentality that's going on. Somewhat immature, but it's what happens.
Also- this is the internet. just relax, man.
