You seem to be so fixated on your personal interpretation that you are unable to read normal English. The antecedent to "them" is in the previous sentence: the white politicians who passed the laws that prevented black people from immigrating to those states, and the white politicians who passed laws preventing black people from living in so-called Sundown towns. Those are specific people, with specific names, if you wanted to look up the legislative record. This certainly is NOT "white people". This is a question about history. In US history, Mexicans, as an example of "Hispanics", WERE NOT CONSIDERED WHITE. Had you read the Wikipedia example of Sundown towns you would have seen "No Mexicans After Night". Had you read the Wikipedia page on CRT you would have seen LatCRT as a subfield of CRT, at https://en.wikipedia.org/wiki/Critical_race_theory#Latino_critical_race_theory https://en.wikipedia.org/wiki/Critical_race_theory#Latino_cr... . Since you don't seem to understand the history, don't seem to track down relevant references, and since I can't seem to make myself understood, I see no point in continuing this discussion
