I am going to ignore the political stuff at the start because I think that is kind of going down a path we already have (conservatives overreacting) and focus on the last questions:Your third paragraph sounds awful, scary and would be something that an extreme left would only possibly agree with. I'm a Buttigieg left and those anecdotes are over the line from my POV, especially for grade school.
I've also heard many accusations from my right wing friends about what schools are making their children do before CRT from having kindergardeners explain why it's okay that Mr Potato Head can be a man or a woman (this was of course right after the Potato Head narrative came out) to discussing sexual id (again right after the narrative came out) to the over glorifying of Obama to including Allah in the pledge of alligence to whatnot.
The best fear campaigns are always based around children (understandably so).
But again, I don't have kids in school so I'm definitely not an expert here (which is why I got miffed when it came out that it's not being taught as my only knowledge of this came from this board which said kids have to stand up and apologize for being white. Which shocked and then when it turned out wasn't happening...yeah, I was perturbed.)
I do have experience in the fear of liberal teachings of public schools in that they are cranking out like an assembly line little AOC's and Bernie's (along with the continued diversity of the country).
My gf's dad swore if he could do it again he'd never let his daughters go to Iowa, they would have gone to a conservative college because in his mind, that's when they changed and were brainwashed.
Which leads us back to public schools. How do they manage a common curriculum in different areas of the country?
Do they micro market it or go with a standard regardless if it's in Monterrey or Shoals or Harlem?
What is regional about learning how to read?
What is regional about math?
What is regional about science?
I think that is where the conservatives have the argument that the left side of the aisle is playing games in education. Regionality should not play into the main concepts being taught in grade school. Political POVs should not be in the school and they definitely should not come into play when teaching the topics above. The only place I can really see political views coming into play is history/social studies and even that should not really be a problem until you get into more complexity in high school. Early social studies is: these are the branches of government, this is what they do, here is how a bill goes to Congress.
You may micro market some techniques but what is actually being taught should be pretty standard, particularly at the lower grade levels. I mean, even if we accept Marvin's argument that institutional racism impacted blacks and we see those impacts and etc. Why the hell is that so important to makes sure it reaches 10 year olds? Really, how important is it that it reaches 16, 17, and 18 year olds? "Because it will cause racial awareness". Anecdotally I would say it is causing far more harm than good.
Most parents want their kids to come out of school with basic skills. I don't see how or why CRT/antiracism/etc. should he part of that equation.
