Moliere had a character in a play who was terribly surprised to learn that he'd been speaking prose all his life.
Today Trump told democratically elected, native born Congresspeople to go back to their "own countries. Like Obama who he insisted had to have been born in Kenya, these women just happen to all have brown skin. There's a pattern here and guess what? If you support that, like Moliere's character surprised to learn he was speaking prose, you might be surprised to learn that you're racist.
