No. I don't see what the point of that would be. I also don't see the point of letting people be anonymous on here (that's why you get the repetitive questions and those people who personally flame boards).
If someone has an opinion that they know or think will warrant a lot of "hate", they can keep it to themselves or find a "tactful" way to let it out. But other than that, you'll just get a lot of people asking "Why do white girls only go out with black/hispanic men instead of white guys?"
