Here's what we're not taught [about the Declaration and Constitution]: Those words at the time they were written were blazingly, electrifyingly subversive. If you understand them truly now, they still are. You are not taught - and it is a disgrace that you aren't - that these men and women were radicals for liberty; that they had a vision of equality that was a slap in the face of what the rest of their world understood to be the unchanging, God-given order of nations; and that they were willing to die to make that desperate vision into a reality for people like us, whom they would never live to see.
