Lawrence G. Proulx has done a great job developing an old argument that if countries like America and Australia are so racist, then why don’t the diverse leave and live in more suitable non-White countries? Of course, this “go home” argument is mainly addressed to African Americans, but the same logical point holds. Proulx did some empirical research and contacted immigration agencies to see how much emigration was occurring from America to Africa. If America is a white racist nation, one would expect a lot. But contrary to Black Lives Matter, there was not enough to be on the statistical radar. Much the same would hold for the recent immigration groups to Australia as well; the pickings are too juicy here, at last for the time.
So, like much else, the anti-racist ideology, is but one more piece of propaganda.
