You left out the part where they thought they could trade their latino heritage out to become white adjacent. The same thing happened with the Irish and Italians. Thats where it all came from.
Foreigners that immigrate believe that classism is the main divide of The US because thats how it is in their country. Ethnicity, religion, and class are the main dividers in countries where everyone looks the same. America was founded on whiteness being the MAJOR social divide and you could trade in your ethnicity if you looked a certain way. Its why if you're Polish no one looks at you funny in the US but in the UK Polish immigrants were part of the propaganda of "Stealing our Jobs" for Brexit. They're finding out the hard way that it doesnt work that way here
Incredibly late reply but they arent known because western feminism still operates on a capitalist mindset where there is no class equality. Why would white women unite with other races when historically they have economically exploited them?
