Isn't it great that they "brought us along"? It took almost another 200 years to even get anti-discrimination legislation for those that supposedly had some "unalienable" right. They didn't bring us along very quickly, did they?
You fail to address my point. Tell me about the "unalienable right" of Jefferson's, and the other FF's, slaves to "life, liberty and the pursuit of happiness". Obviously, that right was VERY alienable, as the slaves did not enjoy those rights. That was nothing more than a selling point for revolution for TJ and the boys. Glad they did, but it doesn't make it true, does it?
As I said, aspirations are noble. For example, Trump may aspire to be an admirable, honest and trustworthy person. Still, he is a lying piece of human feces. Aspirations aren't necessarily truth.
