Those "bottom feeding native sons" (I'm not denying they exist)
don't have another country they can move to if things get ugly, but the Muslim lady does. That is the difference.
What you suggested doing is actually illegal, and for a good reason. If you exile someone from their own nation (as opposed to a member of another nation, who can always leave) they are effectively rendered stateless. Also it is illegal to destroy a nation "in whole or part", though this element of international law is
very selectively enforced (e.g. Rohinya vs Afrikaners)
I would argue that in practice, immigration can do this. You see, unless immigration levels and sources are strictly regulated, demographics can change to the point where an ethnic or racial group is overwhelmed, and thus culturally and politically disenfranchised by invaders.
This is beginning to happen in many parts of Western Europe. I bear nobody any ill will, but as you seem enthused by the thought of white people being bred out or exiled from our ancestral homes, I think it's fair enough to call you a racist.
