The professor has endured, and responded to, the first stage of grieving by which the United States is adjusting to its new status in the world: denial. The Christian right, terrified because warnings about "Ghodless Commies" and "Yellow Peril" and "Al CAYDA!" aren't bringing in the money like they used to, is now resorting to the time-honored tactic of trying to shout their opponents down.
Of course, what's important is the next step: if the professor finds his windows shattered during a twenty-first-century Kristallnacht, then we'll know that America has slipped over the edge from "denial" to "anger" and is sliding down the long slope to totalitarianism.
Of course, that can't happen here.
