From an outsider's perspective, at this point in time I'll wager that any sort of nationwide civil unrest in the US akin to a civil war won't be a whites vs blacks scenario, it will be a Liberal vs Conservative one.
Consider how many mindfucked whites there are in Blue states, similar to the leftard mongoloids on here, who are disciples of globohomo and would eagerly bend the knee in respect for the Soviet hammer and sickle or the degenerate rainbow fag flag, if either were flown in place of the stars and stripes over the White House.
Then you've got latinos like Flea and Biggie who are completely opposed to that shit and fall into the right wing Patriot camp, along with Somoans, Asians and all kinds of races who march with the Proud Boys and regularly destroy the worthless Antifa soy cucks.
So no, in the US at least, a "race war" is not on the cards, it's a war of ideologies, and naturally, I am rooting for the Patriots.
