1. I do not think that we can compare the situation here with South Africa.
2. Non-Caucasians are the overwhelming majority in S.A.
3. When Caucasians become a small minority in this country by the end of this century, I do not think that they will be put in concentration camps.
a. Non-Caucasians (most of whom will be Hispanic people) will have no desire to do so.
4. I think the United States will just become, say, Los Angeles (my city) writ large.
a. That is to say, the government will be run mostly by Hispanic people (who are on track to eventually become the majority) and some African Americans (who will be much smaller in numbers than Hispanic people).
5. The United States of America will become, IMHO, a violent, corrupt, & disorganized country. The Caucasians who still live here will adjust, as they have in Chicago, Baltimore, New Orleans, and other such cities. Of course, some Caucasians will emigrate, but I have no idea to where.
6. In short, I respectfully disagree with those sincere "liberals" who really, really, really believe that once Caucasians lose their predominant position, this country will become a Utopia of brotherly love, as is portrayed in TV commercials.
