We can imagine a bell curve called the "Thought Pile" that represents public opinion on any given issue at a given time. The story of interracial marriage is a story of the Thought Pile steadily moving over time, like an organism. As it moves, the Overton window moves with it. https://t.co/ZpSJGgdGHf — PolitiTweet.org
