This is a sorely-needed and well-written addition to the conversation on teaching about race in schools! I think you're absolutely right: even when CRT is not literally taught in schools, the ideas can be found in instruction to varying degrees, and we shouldn't hide from that.

However, I think you overstate the extent to which the tenets of CRT are not taught.

Here are some curriculum goals which are linked on an official resources page for some educational jurisdiction.

"Identify the motivations, tools, and implications of power, authority, and governance as it relates to systems of oppression and its impact on ethnic and religious groups and other historically marginalized groups."

"Evaluate the influence of the intersections of identity, including but not limited to, gender, age, race, ethnicity, religion, physical and mental disability, and class"

"Understand and analyze the impact of systems of power, including white supremacy, institutional racism, racial hierarchy, and oppression."

"Explain why individuals and groups*, including ethnic and religious groups, and traditionally marginalized groups during the same historical period differed in their perspectives of events, cycles, or movements in the United States."

"Analyze and explain the multiple perspectives of ethnic and traditionally marginalized group to investigate causes and effects of significant events"

It doesn't quite contain every tenet of CRT, but the resemblance is substantially greater than with your examples.
