The radical demographic shifts taking place in the United States today are due largely to immigration, not birth rates, and immigration can be controlled. The dispossession of whites is not inevitable, and it certainly isn’t desireable. Unless maybe you just hate whites. (That’s a generic you; I don’t mean to imply you hate whites.)
If you don’t mind most of the country turning into Detroit and South Central L.A., I guess it wouldn’t make any difference to you. But anyone who doesn’t care about his children and grandchildren living in such a country has something horribly wrong with him.
