There are two points about that theory:
1. Whites are no longer the majority. The "all others" category is over 51%.
2. White America is now a nation of herbivores - completely beaten down by PC and fear. There will be no rising up.
I acknowledge your points are well-founded. Perhaps I’m being optimistic, but I just don’t see Americans — unlike modern socialist Europeans — standing by while their assets and livelihoods are taken away and, ultimately, their family’s personal safety is threatened by savages.
