You can call it "science" but your beliefs have more in common with quasi religious articles of faith. CRT is an area of study no different than theology. Aggressively proselytizing your religion is not as effective as you think, see the jehovahs witnesses. Lots of people feel their god is real and think non adherents are delusional, some even try to prove their god is real with "science".
Have you done any research into it? Or, because it makes you uncomfortable, you just write it off as a religion and ignore it?
A lot of people work backwards. They don't like the conclusions drawn by CRT and social studies so they work backwards and conclude that it's based on things that aren't real. But these areas of studies work forwards. Meaning, they identify obvious, real, and undeniable racial systems, such as redlining, and then study the long-term effects of that.
If you think something like, say, preventing black Americans from owning property, has no long-term effects on the demographic then you've probably just never thought about it. This isn't a TV show, this isn't a picture perfect depiction of a country. Our institutions are old, and things don't just - poof - get fixed. Integration was messy, and it took decades. Reconstruction wasn't linear, it progressed and then regressed. Segregation never disappeared - to this day, most cities are segregated. To just conclude "well that doesn't matter", based on zero research or understanding, is intellectually lazy.
Of course, if you do start to do research into it, congratulations, you have re-discovered the discipline of CRT. Because that's all it is. So, you have no choice but to stay ignorant, because otherwise you threaten your entire belief system. And we can't have that, can we?
