I am always amused by people who respond with ad hominem.

Jews and Catholics were mistreated because they were not Protestants. They were still legally white and enjoyed all the legal benefits of whiteness. European Jews never had to go to court to establish their whiteness as Middle-Easterners did.

Asians were very much targeted. See the limits on Asian immigration before the 1960s.

My objection to CRT is that it's designed to sow "competition and angst" among people by perpetuating the social concept of race. There's a reason the children of people who once insisted they were white are now insisting they're people of color, and why people of color used to try to pass as white but now white people try to pass as people of color.
