So the end result of what you suport will be one mixed race and one global culture.    I doubt that this would happen if multiculturalism were to push on forever because there are so many people on this Earth that mix with so many different races. There would have to a consitent pattern that happened over a long period of time in what races mix in order to actually come out with one big race. Plus there are people, although mixed, who still have preferences when it comes the races they date and make babies with.    For example, I know a couple of mixed white/asian females who either only date and choose to be with a white or who only date and choose to be with an asian.
