I'm not a ginger, but I know a girl who is one, and I constantly rag on her for being ginger. She's pretty much embraced the whole thing though, even the part about gingers having no souls. Because you know they don't.
What's that? People have already made that South Park reference you say? Too bad.
Also, might I add that calling someone a ginger isn't like calling someone the n-word or anything. It's just a description, like blond, or brunette. So there's no reason to get mad if you're called what you provably are.
