It's unclear to what extent your comment is serious or facetious but I want to point out that even if we ignore the explicit racism, your vision of Latin Americans is also implicitly bigoted and condescending to a very large degree. In "warning" them against Anglo culture you are essentially implying that they are akin to magical innocent hobbit incapable of making decisions for themselves and who should never change so that they can continue accommodating your fantasy understanding of their lives.
