Do you think it's too much of a stretch to propose that NCLB was part of the right's continuing effort to enshittify (word credit to Cory Doctoro) public education until no one will support it any longer? Movement conservatism hates anything public and universal. Public education, social security, universal suffrage, etc.
I'm trying to think back. When did I first learn about The Holocaust? Ah yes. My parents didn't wait for the public schools. They sat us down when the documentary "Remember Us" first aired. Have you ever seen it? Very graphic. I remember being dumbstruck with horror. I was like in the 4th grade.
