White genocide is all-important to both parties, and only very recently are the Republicans making a meek pretense to the contrary. If we were to put “replace whitey” as a policy goal into the left-right political spectrum, it would have to fall FAR onto the left side. If your political party’s overwhelmingly top priority is FAR left, then your party is FAR left.
This isn’t really complicated and I don’t need to debate it. It’s just how it is.
