I don't hate on Alicorn OCs. Some of 'em are cheesy, once in awhile they can be awesome - and even with the cheesy ones, everybody's got the right to make some fun cheese at least once in their life, yeah?
Even in fairly friendly fandoms, fandom culture can get ugly sometimes. >.< It's weird. I kinda get where some debates come from, but if somebody wants to make an OC they think is cool because they love the same show you love, and you disagree about what "cool" means, shouldn't that be a "just back off already and live and let live" point?
