This is an inherent feature of the emerging system where cultural norms flow top-down from college educated professionals (who are far whiter than the population as a whole). That’ll be true even on matters relating to minorities, because it’ll be college educated white people empowered to decide which non-white people get a platform.
> cultural norms flow top-down from college educated professionals
It doesn't flow anywhere except to other college educated professionals. These people attempt to tell rural, or the working-class, or immigrants what to say and how to behave, who then turn around and do something else like elect Trump.
Progressivism is a manifestation of cultural principles that are closely associated with, and disproportionately manifested among, people of white European descent. There are liberals in every country, but the emphasis on say and sexual self expression and self determination is pretty distinct to countries founded by white Europeans.
It’s similar, in that regard, to small government conservatism. There are conservatives everywhere. But the particular antagonism to government authority is uniquely a product of certain white European cultures.
