People can't be controlled, as others have said. There will be some people who mix because it's what they want to do; if they ask me, I'm going to suggest they move on from their nonwhite partner.    Personally, the reason I feel it's genocide is because when it happens at a large scale over a long period of time, it results in a race or ethnicity being eclipsed by another and while some of their culture and traditions may exist, it doesn't leave them completely intact. Secondly, it's not just something that people are free to do or not do, completely of their own volition. Immigrants are being imported, cross-race relationships are shown in the media as an ideal, whites are portrayed as total wimps and losers while other races are shown in a flattering way, college courses dissect how problematic whiteness is and cultivate guilt, etc. It's influencing people who, left to their own devices, would probably just partner off within their own race, to choose partners of a different race instead.
