I have a somewhat biased view on this issue. I tend to agree with the element that seeks to introduce this as scholastic for all levels of learning. And though there are politics involved, it simply requires the discussion around racial & ethnicity relations to evolve. The politics though, may change as a result; at least for future generations, and I can see what they disagree with but I disagree...
When I say that, I mean including ethinicities, or more people without excluding anyone based on racial bias, or in some cases nationality. I think what we mean (what society means) to do with critical race theory in curriculum is create a new norm of "inclusiveness", or of equality that allows for an easier interpretation for our children or for young people in general. When you introduce something in that context, rather than another medium (say network television or cable news) you provide a way forward that doesn't ask as many questions... It allows someone to absorb critical race theory (inclusiveness, equality) lessons the same way we would absorb a grammar lesson. The facts are presented, and the mind doesn't really ask, "Is this really true?" or "should I commit this to memory?". So, what we begin to see is a departure from attitudes (and as a byproduct voting behavior) that involve prejudice in ethnicity or nationality and gender or sexuality too. To introduce that in an elementary math lesson, in my opinion, is hardly controversial.
My understanding of critical race theory is that it involves the law and race, not inclusiveness. In CRT, race is a social construct, not a biological one. It looks into how social interactions affect "neutral laws" such as the fact that possession of marijuana is prohibited to everyone in certain states but a disproportionate number of non whites and poor are actually convicted of possession. CRT is only taught at a university level so it has nothing to do with children.
And it's five million years ago. LOL. Poor Florida is the only one with the right idea! Here I am, standing my ground... FOR WHAT? An outcry to follow.
