Far right I can get behind. You HAVE to get behind "far right", considering the current position of the Overton Window in present year. But ethno-nationalist?
I can kind of understand the need for present-day America to split into two countries at least (namely: Woke-Liberal-Insanity and traditional family values America) to avoid a repeat of 1861-1865, but I fail to see how an ethno-state would work. How would you determine who is "pure" enough to be a member?
