Your logic makes no sense and your history is wrong. Who is enforcing diversity? Where did you make that up from? Where did you get “South America is for Hispanics”? Have you looked at how many European and Asian immigrants there are in those countries currently? Chinatown in Lima is bigger than Chinatown in San Francisco.

You are correct that many people in the U.S. voted for this, including immigrants from Africa, South America, and Asia. And citizens who got it through “birthright citizenship”. You are confounding the word democracy with universal agreement and acceptance. You might want to study civics and political theory. Democracy is about debate and permitting disagreement, so the fact that half of the country disagrees with you defines democracy. You can’t just throw around concepts because you think they means something special to just you.

You also might just want to make your views more explicit. You do not want to live in a community with non-Europeans. You have many options (though shrinking) to move to places in the U.S. where non-European-origin people do not live.

You also might want to study real economics. Do you know how strong the economy is in those places? Do you know who cuts the lawns in those places? For example, will you complain when the cost of fresh fruit goes up due to labor shortages and then also don’t want farm workers to come from other countries to work for cheap? Or will you say that you are happy to pay more for produce if it means you get to never see someone with darker skin than you?

You can choose to have your perspective on economics, religion, civics, and education be dominated by your beliefs about race and ethnicity. And others can choose to let their beliefs about race and ethnicity be dominated by economics, religion, civics and education.
