Gender though? What cat supposed to be all gay? Lol. When you have a racial preference something is usually wrong somewhere IMO. Everything else outside of gender that you mentioned would be across the board so that makes sense. Personally I don't care but its not just a simple preference IMO
Gender as in Gay
I do agree that in some case it has to do with more than preference, like stereo type.
White girl like black guy because they have big D's.
White guy like black girl because they have big butts.
Black girl like white guy because they are more generous.
Black guy white girl, because they don't have attitudes ...
We can go on an on ...
does that make them racist? Just mean they are stereo typing and probably base on their life experiences they develop these preferences.
Are some meaning - no black guys because I want to keep my blood pure or vice versa .. yes, but its not always the case.
