It's a preference.
I am not racist, yet I am mostly attracted to white guys , becuase that's what I've been surrounded my whole life with. However, I am also very attracted to some black guys, like a lot of them are so ****ing hot to me. I am rarely attracted to latinos, but some of them are so ****ing hot as well and i am like
And I am even more rarely attracted to Asian guys, but sometimes it happens.
Doesn't mean I am racist. (I'm white btw).
I have a friend who don't like white guys with dark hair etc. (unless they are really hot) he says they are too dark for him
He really prefers blonde guys with really white/pale skin. He is not into black guys either
And he is not racist, he is very open minded etc.
I'd never limit myself tho, why ?
But there is always something fishy when you just exclude a whole race, just like that u know. . . It's not necessarily racism, it can be prejudice, it can be ignorance etc. (although those characteristics form the term racism, but still it's a bit different)
