Most white Americans, even the best intentioned liberals, don't realize that Mexico still has a lot of problems with colonial hierarchy in their own country. Internalized colonialism is the hardest kind to break, that's why there's fuckheads like the Latinos for Trump. I didn't think about that bit about teachers, but now that you say it a huge percentage of latinx students I knew in college were going into education. The school system in America is still an organ of colonialism, but at least in my neck of the woods we're going through the growing pains of bringing in new teaching methods.
