I might piss some people off with this one. But I guess you could say I'm a southpark purist. I don't have a problem with creating a character for a story, but when you create a RECURRING character and end up turning every fanfic you write into something that's not really southpark, but rather a spinoff of it it just kind of ruins the whole gendre for me. That, and I'm really sick of the whole "pinwheel" thing. It's kind of retarded.
Just my $.02
