"For a radical progressive who once harbored negative stereotypes about folks on the right, it was a turning point for me: Though Sean Hannity or Sarah Palin and I disagree profoundly on politics – they're personable, kind, and human. If you want to persuade people, you can’t demonize them."...
Sally could have learned that lesson simply by reading the writings of Thomas Jefferson, specifically a letter he wrote to Richard Johnson over a hundred years ago, in which he said, "It has been a source of great pain to me to have met with so many among [my] opponents who had not the liberality to distinguish between political and social opposition; who transferred at once to the person, the hatred they bore to his political opinions."
Of course, if Sally had indeed read the writings of Thomas Jefferson she wouldn't have ended up as a "radical progressive" either, but that's an entirely different discussion . . .
