It has several tenets, I think. One of them you mentioned ("intersectionality"), which basically means that it's the white, straight male against everyone else. Some might throw "Christian" in there. If you leave that part out, like Caryn Elaine Johnson did, you get a slap on the wrist but you don't lose your job... at least, not if you're black.

The other big tenet is this "systemic" accusation. In short, it's not enough to let them sit where they want and use our bathrooms. It's not enough to grant preferential admission to college or the job market. The whole damned thing is built on bigotry, and we have to tear it down.

It's starting with statues, flags, and sports team names. Look for Mt. Rushmore to get some kind of "context" soon, like a plaque about how whitey is mean and shouldn't have made this. The Electoral College is definitely on people's minds, and states like Colorado have even found ways to circumvent it locally.

How far does this go? I can certainly imagine the extinction of the white race as a discernible thing. Places like France and the USA will be ethnically more like Brazil or Mexico are. (You run into Anglo-Saxon-looking people in Mexico, who are native to that country and descend from natives, but the odds of two of these people meeting each other and, say, marrying and moving into a mestizo-free neighborhood have become extremely low.)

Another possible outcome is a white backlash that reestablishes Anglo-Saxon hegemony over the things those people are good at. Or maybe the backlash just reestablishes the right of white people to take pride in their race and its accomplishments and talents. Having to run off mobs of black people with rifles or be raped and pillaged might wake up a few white people. That's already starting to happen.
