Some good points. But though sexual attractions and racial support or lack of it (racism) very often overlap, they are actually very distinct. Sexual attractions can be exploitative and merely lustful whereas supporting a race is more of social-cultural activism. Sexual dalliances can be limited to social bias (i.e. status), exotic nature (of certain races) or simply sexual preference as in fetich.

So one can marry a different race because they are attracted to that one person in particular, but at the same time look down on their corresponding race. Similarly, it is not uncommon to see individuals of a race militate against their own, subtly or even overtly as a result of perhaps ignorance or as some content self-hatred. It can be a complex topic altogether.
