You're 100% correct on this. However, you are missing an important piece.

There's no way to get the word out. Any speech mentioning Jewish overrepresentation will be banned from all major platforms. Too many of these organizations are beholden to astroturfed Twitter mobs and rely too much on Facebook engagement trackers to get feedback from their base. These platforms will remove or demote posts that critize Jews, so there is no feasible way to grow awareness in time

Embracing CRT leads to the downfall of Whites in the short term because the CRT figureheads are Jewish, so tacitly supporting CRT as a White person will screw over Whites. By the time, the Jews are exposed as overrepresented there will be no Whites left.
