Also, fun and entertainment or not, what your producing is essentially art, and it should be as close to your definition of perfection as it can be

See- I don't agree with THAT. Fanfiction is not necessarily art. It certainly CAN be- but it isn't just by it's definition.

If you're going to that picky about it - you could go further and say that people shouldn't even make journal entries that aren't obsessively edited. Where do you draw the line?

You can certainly choose not to read anything that isn't college English good- because you're not interested/don't get anything from it, but I don't think you should put that judgement on others.
