Multiculturalism is taught since grade school in America and is seen as the only way to structure a society by most in the country. I actually often get called a racist when I mention to other people that it isn't the only way.
edit: I do find it interesting that this comment was downvoted. For those of you downvoting me, could you please explain why? Was my critique on multiculturalism not the reason my post above was downvoted?
