Why is it that whites have to give up their countries lest they be considered racists? Where is this obligation from, that is so unique as to afflict only whites?

Maybe it's a biological response, that foreign groups attempt to subvert the dominant given the slightest moment of weakness; perhaps that's inevitable. If you were truly vying for a society that is not detrimental to the host, nor intolerant of different people, it has to be a society where the host people are unabashed, unrepentant, and steadfast about who they are; are the prevailing majority and conscious; the minorities must submit to the host - it cannot be done any other way.

The pain and anguish will soon turn into anger, and then no one is going to care to be called racist, and they may even be just that.
