Dems need to do something to counter it. Be it a "national history position" or something like that. When I talk to friends who are moderate Republicans (like I used to be once) they don't mind history being taught. Where they have an issue is the belief that CRT teaches "it's all white peoples fault" and that "racism still runs everything". They take that as saying they are racist, which they object too, and that is where our problem is.
If I were a history teacher today I'd be teaching the REAL and COMPLETE history of the United States. Starting with the Pilgrims coming over and finding the Native Americans. I'd talk about Thanksgiving but also talk about things like Smallpox, the Trail of Tears, putting the Indians on reservations in the desert and the poverty. I'd talk about bringing African people here as slaves on slave ships. I'd show the movie Amistad in class, maybe Roots too if I could get away with it. Talk about the Civil War in detail and show them the Underground Railroad history. Then about WWI and WWII and how there were separate divisions based on race. I would highlight both and the benefit they provided to ALL Americans. The right to vote, the protests, Selma, MLK, redlining and desegregation.
Actual "history" that is factual. Not blaming anyone. Let the students figure it out for themselves. They're going to notice "hey... it looks like white people did all this nasty stuff". I would never come out and say it, nor would I blame things today on racism, but actual history is the proof in the pudding.
