In my estimations the left can't really sustain protracted fighting. Not enough actual fighters. Look at what they're comprised of. Gays, effeminate metrosexual guilty white males, drug addicts, lesbos, trannys, spoiled Stupid rich kids from the affluent suburbs and naturally black people. I don't see Hispanics throwing in for this, they really don't give a darn about American cultural issues. They'll watch out for themselves and enjoy watching the spectacle from the sidelines with a cold beer.
The lesbos are probably the toughest of them after the blacks which they'll use as cannon fodder. Once they run low on able bodied black males who aren't incarcerated what's left really? The gays? Oh scary.
Their white males may contain the odd ex military members but really they're all emasculated from being shamed and guilt tripped the last few decades for their toxic masculinity and white privilege. Groveling at the feet of women, gays and blacks for so long like whipped dogs they're of little use except as suicide bombers at best.
Then there's the trannys which are mostly dudes and they usually have a bit of feist to them but their numbers are so few.

The left wants a fight but to not have to actually fight in it so it'll be all the suckers they can get to fight for them. All the angry victim groups whose dire they've been fomenting with their divisive social justice, identity politics and race baiting brainwashing.
Once those pawns are gone or surrendered there will be a hasty retreat back to their gated communities and Ivy League campuses to lay low until it's all blown over so they can start the next phase of their psychological warfare campaign against the population.
And anonymously sow the seeds for their next great bloody revolution they won't spill their own blood in.
