The United States was founded on the notion that all men are created equal and have some unalienable rights, including life, liberty, and the pursuit of happiness. The part about the pursuit of happiness is a particularly American idea. It’s something we should be proud of.
We’ve made mistakes. We’ve gone off in the wrong direction. Sometimes we’ve been on the wrong side of history. Sometimes it’s taken us a long time to figure things out. But eventually, we recognized that the notions of being created equal and having unalienable rights applied to everybody, not just to men, not just to people who were free, not just to people who owned land, not just to people who looked like the people in the majority, sounded like the people in the majority, went to the same churches as the people in the majority, and had the same prejudices and biases as the people in the majority.
