That’s how it’s worked for nearly all of history. A decent read is this book (which was on obamas summer reading list one year): https://www.amazon.com/Great-Experiment-Diverse-Democracies-.... Diversity has never really worked before.

Diversity has historically been used to keep populations divided allowing a smaller group to rule over them. Plenty of historical examples (Italy, Ottoman Empire, etc) as well as literature. I think this is described in Machiavelli’s “The Prince”.

And both current US candidates are pushing for immigration/diversity (albeit from different groups, but the end result is the same). The real reason we can’t discuss politics is because our elites want us divided, and they have the means to accomplish that.
