No, but I don't really get people who feel the need to always broadcast what they're not attracted to. I can't explain it, but I don't think anyone really gives a **** what/who you're into.
I don't think so..Everyone has his preferences...
I'm particularly attracted to blond hair.That doesn't mean I discriminate the other ones.It's just my own personal taste.
Yes because it means you view that entire race as a monolith. People of a certain race don't all look alike or have the exact same physical characteristics, writing off an entire race as if they do is racist and very shallow.
But I will say, there is a difference between saying "I normally date x race/ have only ever dated people of x race" and saying "I refuse to ever date y race". The latter is where the racism is clear. The first is not racism because you're leaving options open.
