What's so wrong with Critical Race Theory and the 1619 Project? They are eerily similar to what Mao used in 1966 to turn students and the masses against everything in China that was old and foundational. (Old Ideas, Old Culture, Old Habits, & Old Customs ) It was a manipulation that threatened all who opposed it, just like is happening today. No critical thinking allowed. Wikipedia says, "Sweep Away All Monsters and Demons", where the Old Things... "fostered by the exploiting classes ... have poisoned the minds of the people for thousands of years". https://en.wikipedia.org/wiki/Four_Olds
Sounds just like the 1619 Project and their accusations of 400 years of "systemic racism" and "White supremacy" and nothing to be proud of in American History or our Constitution. But our Constitution has protected our rights and freedoms and has made America the land of opportunity and hope. We must think and speak clearly on this or risk losing it altogether.
It allows those in power to sweep away all the boundaries, because anyone can be taken down if they don't go along. No one and nothing is safe. That's why it keeps getting worse and worse and so unreasonable. We see people losing their jobs very suddenly over words and ancient history. It pretends to want to make things better for minorities, but it doesn't, but who dares point that out?
Great info on the subject available from James Lindsay at https://newdiscourses.com/2021/12/five-key-points-to-understand-about-critical-race-theory/
He also brings up the negative impact on students, because they no longer focus on the skills and knowledge they no longer respect. Even math and logic have been accused of being too "White".
