I generally try to ignore the "hot button" things that certain media platforms and the people that read them scream about, so I honestly don't know what "critical race theory" is about.
So I looked it up. from wikipedia:
Critical race theory (CRT) is an academic movement of civil rights scholars and activists in the United States who seek to critically examine the law as it intersects with issues of race and to challenge mainstream liberal approaches to racial justice.[1] Critical race theory examines social, cultural and legal issues as they relate to race and racism.
So...
Critical race theory is loosely unified by two common themes: first, that white supremacy, with its societal or structural racism, exists and maintains power through the law;[6] and second, that transforming the relationship between law and racial power, and also achieving racial emancipation and anti-subordination more broadly, is possible.
I suppose that could be a good thing, depending on how it's done and implemented.
Since I believe, based on the documented evidence, both historical and current (the latter helpfully provided for the board by Gulo's posts on inherent & unconscious bias) that racism has been and continues to be a problem in this country, and racism is - if not solely taught at home, then strongly reinforced at home - schools should have a role in countering this, and hopefully after a few decades we can undo much of the harm that's been done.
Why is this controversial?
