I actually wonder if the Alt-Right changed their message to focus more on exit rather than revolution, how the public attitude towards them would change. Like, if their fundamental thesis was something along the lines of this:
“In order to secure the existence of our people and a future for white children, we would like to have our own Amish/Indian sort of deal where we can peacefully withdraw from a society we find repulsive.”
Obviously by and large it would still be offensive to hardcore lefties and true believer progs, but how would it impact the moderates, the average joe? What about the free speech/gamergater/cultural libertarian crowd? Certainly it wouldn’t make them more willing to adopt the alt-right’s white nationalism, but would the idea of giving these people an exit from modernity be seen as more reasonable than them wanting to take over the US and make it a white ethno-state?
What you have to understand is that everyone in politics is incompetent and ideology-huffed. In part, because if you aren’t, it’s hard to derive enough motive power.
So, while “White People Reservation” is an order of magnitude more achievable, and two or three orders of magnitude less damaging than “make the US into a white ethno-state,” they aren’t going to take it up as their rallying cry.
