Maybe they can form their own army, call it say, the "Confederate States of America army"?
If you look at the makeup of the modern American armed forces you will find a disproportionate number of minorities. Most racists can't make it into the forces today, unless Uncle Sam needs warm bodies for an ongoing war. Most racist nazi assholes like you can't take orders from African American officers, sergeants and corporals, you can't form cohesive fighting units, militaries run on trust, and your kind can't be trusted. When the forces are being selective (most of the time), racists are screened out, after all, they did turn out to be traitors by continuing to support the traitor Trump. Those racists left in the military will be soon turfed out and are generally not promoted anyway.
Racists like you have been proven to be a national security threat by your support for treason, by willingly spreading foreign sourced propaganda and disinformation. Racism is now widely perceived as a national security threat and will be treated as such moving forward, that is gonna mean hate speech and crime laws. If your busted for these class of crimes it will probably mean a lifetime firearms ban and possible disenfranchisement for these particular crimes only though. When you lose in 2020, you will lose a lot more than realize now, but you will howl and dance when the day arrives, but that's about it.
