I have a friend who has done this with the Zoom classes. One English teacher was talking about how evil white men are. She called the principal and superintendent and said she was offended. Her daughter was fearful the teacher would treat the white kids differently. Also added that the teacher was creating a hostile environment for the white students. The teacher toned it down some.
The next time the teacher tried CRT in the classroom, the daughter asked why she hates white people so much, especially since teacher is white. Teacher denied she hated white people.
I’m surprised some pissed off parents didn’t show up at the school and kick that “teacher’s” ass.
