The core idea of CRT is that race is a social construct, and that racism is not merely the product of individual bias or prejudice, but also something embedded in legal systems and policies.
And do you know what? I think that's actually quite correct.
You know, I've been thinking lately that we humans are faced with yet another crisis (in addition to killing the planet we live on, which we might come to regret). That crisis is that our world has also become far, far too small for our ability to modify our social constructs so that we can get along. And a large part of that -- though this will be a reason for many to hate my thought -- is because we made it that way. We built the ships and paid the costs to enslave people and bring them across the seas to make our lives more comfortable. This is simply the truth, and it is irrefutable.
Throughout human history, we seem to have divided ourselves up into people who are "liberal," "conservative" or "independent." The latter being those who don't know themselves well are can go where the crowd goes (maybe they're the ones that can tip the balance between a vengeful throng lynching somebody, or disbanding).
But this "liberal" and "conservative" thing is the conundrum. Forget party names -- in Lincoln's day, the Republicans were the more liberal and the Democrats the more conservative. Names, like all human words, change their meaning with time. "It's why so many people hate trying to read Shakespeare!) In my view, a "liberal" is someone who is not unduly uncomfortable with diversity, who doesn't cringe when someone has a different view of social norms, or different food preferences, or a different skin colour or physiognomy.
(It's interesting to note that studies have shown that liberals are significantly more likely to enjoy (real) ethnic food than conservatives.
Conservatives and Liberals Make Different Food Choices)
In sum, a think that CRT is correct, that racism is a social construct -- and that it is primarily the construct of those who have much more difficulty dealing with diversity, who are more comfortable with conformity, who are less amenable to being open to new experience -- that is, conservatives.
