No. I dont think its racist. I am attracted to certain races more than others. This doesnt mean I would rule out a relationship with the races Im not attracted to, and it certainly doesnt mean I wouldnt be friends with those people.
Being attracted to certain races is no worse than prefering blondes over brunettes.
I like white people, as well as asian, and obviously Jews and Hispanics. I like lighter black people,but not so much very dark blaxk people.
For some reasonIm very attracted to Indian/Pakistani people, alrhough, obviously without the religion.
