Blue grass eh? What the hell? I have never heard of such a thing, and I suspect the people who downvoted you hadn't as well.

Also: >Why are Europeans White? Because none of them are Wong :-) and there not actualy white.

This is not the kind of serious scientific discussion expected here - you're supposed to be making some kind of point. You're not explaining anything by saying "they're not actually white".

Also, sadly, I think people downvoted you because of your grammar - you don't seem to be a native speaker, you're making some odd/un-intellectual mistakes.
