People know...
Not just Americans, but the entire globe.
People know that the founders didn't mean it then, nor does
this nation mean it now. Sure the words were written down, and our leaders frequently
point to them as evidence that we are good. But no one really meant them. They
were merely a means to an end.
Back in 1776, when representatives from a bunch of colonies
wrote the words, "We hold these truths to be self-evident, that all men are
created equal," they did not literally mean ALL men.
But people know that.
