There are some people, believe it or not, that are evolved enough to not only accept differences in people, but choose to be friends and even family, spouses. Now, would someone actually propose that people who love each other, family, spouses, friends, should be split up into different areas merely because they are different races, religions, sexual orientations, or hold different political ideals? That seems to be the idea here. The unevolved, the bigoted, the ones unable or unwilling to peaceably get along with and accept people different than them, wanting to propose the idea that people should be separated from others based upon their own ideals and prejudices. That isn't accomplishing anything but moving society backwards. We move forward together, as a human race, or move backwards towards destruction as separate groups set against each other.
