Even the so called Neo Nazis of our society the alt right believe all men are created equal.In a nation that believes that all men are created equal, we still have large segments of the population that can't or choose not to accept this fundamental truth.
I also suspect that minorities in many nations are piped down by the majority.
That's how fundamental a belief it is that we all share and a sign that the US and white people in particular being the majority are far better than anywhere else.
As you said in pretty much all other cultures the minority are piped down by the majority. They don't give a damn and we do. People should always remember that.
