Does it even make sense to say the Overton window shifted one way or another? The claim is meaningless without also including whether the window widened, narrowed or stayed the same width. The whole point of the window is that it defines the left and right bounds of acceptable discourse. So does "shift right" mean that both the left and right edges shifted to the right? Or that the left stayed in place while the window widened to the right? Or that the right stayed in place while the window narrowed toward it?

All good points, but I'm interested in any examples of a rightward shift. What are we talking about here, specifically?
