I am waiting for the domestic terror groups BLM and Antifa to apologize to everyone. Yeah, I know...when monkeys fly out of my butt.
That kind of crap shouldn't be going on in schools. Kids are divided enough without the teacher adding to it no matter what the basis and no matter which side is "praised vs. criticized". As to speaking about abortion and birth control, that should be part of sex ed that parents can opt their kids into (separately, as some parents might be fine with one and not the other). You can't teach history without teaching some religion, but this mess sounds like it was something else entirely.
The only reason to separate them is to debate with the teacher as moderator keeping it civil. Then at the end have a lesson on how important civil discussion is and even in disagreement we are still Americans. She probably went full marxist including censorship.
That first guy getting the bell to the head was my favorite part. He threw a sneak punch and didn't realize he fucked with the terminator. If the police hadn't showed up he would have shoved those scooters up their asses.
