Open Question: Is it racist to turn down a person for their race?

I mean by dating or love. I only like White girls because I find them attractive. I am also White. It's just that at school, there have been a lot of Asian and some Hispanic girls asking me out. Yes I do decline them because of their race. I also hate it how the Asian girls think they can charm any White guy, they even go as far as ignoring other Asians. It's not wrong to want to preserve my culture or go with my taste, most people do it. So to not be racist, you must offer yourself to people you don't love? I am willing to be just friends with other races but not love.
