I agree -- My little pony has gone too far. Being in 10th grade, I can vouch for the fact that you can kick his ass, he deserves it. MLP was originally, AFAIK, a show, but it quickly spiralled up and it's now an object, fuelled only by hype. That's not the kind of thing that lasts very long though; it'd quickly die out, but the problem is that there are too many people who like the hype, so every time it seems as it's going to die down, another fanatic opens it up.
It's like a fever -- I get infected, and then soon after, you do, and if I heal, then you'll reinfect me. The only problem is that unlike a fever, this MLP thing cannot stop unless we really make a conscious effort to stop this problem.
And yes, as I mentioned before, you can kick his ass. I doubt others will have the courage; they'll be pounded by the fellow bronies. (Kids can be a fatal lot in groups, especially if they're younger than you)
