I get the argument, sort of a reverse of the Left's "long march through the institutions", I really do. But I also think that ship has sailed. The Western world has imported hostile demographics keen on replacing what they see as a decadent, enfeebled host culture. They are breeding fast and we subsidize this with the welfare apparatus; meanwhile the indigenous citizenry of the West are not reproducing at even replacement levels. Combine this with the political machinations undergirding this whole state of affairs and it leads me to conclude that we have nothing like the 80-100 years that it took for the Left to infest our institutions.
I guess you could say I'm something of a catastrophist, in that I believe our only chance lies in some sort of upheavals that upset the paradigm enough to permit a course correction. The nature of these upheavals could be anyone's guess, but almost certainly global economics will play the big role.
More. Faster. Please.
