The big screen and real life are self-excluding. T.V. programs are not an objective representation of reality. Most people date and marry their own ethnic groups. Gosh, I'm starting to think you're trolling. For example, in Russian 93% of Russian men marry russian women. It's 87% the other way around because of the scarcity of men in Russia. For 10 women there are only 9 men. So that one example dissproves your theory.
