I dunno if I can do your steps: you are a much better sequential/linear writer than I (it's a compliment, I promise, don't argue with me plz), but here's what occurs to me on what you say:

1. CRT frustrates the modern impulse to individuate human sin into discrete acts

1b. instead arguing that racism/white supremacy can't be broken down into "you did a racism right there" moments

2. CRT names the system/structure of White supremacy as part of the problem in seeing racism. Since we live in it, we are blinded to it. But...

2b. The modern frame privileges itself as superior/central to all other frames of reference. It's enlightened, advanced, sophisticated, non-primative. To admit that it's fundamentally deficient in some essential ways is contra-modernities narrative about itself.
