And sounds like you have a "know better than thou" problem.
You seem to want to impose your ideas of society on everyone else. Freedom of association is a corner stone of a free society. Would you have your multicultural jack booted stormtroopers break down the airlocks of every space colony to enforce your diversity quota? If the entire solar system isn't big enough for you to allow a multitude of differing societies, then you are the one with a problem, not me.
Wanting to satisfy your hormonal cravings for exotic ass on demand isn't reason enough to throw society into ethnic chaos.
