Godwin's Law is the humorous maxim that asserts that, the longer an Internet discussion continues, the probability of someone raising the Nazis or Hitler approaches 1.
As I noted over on Will's blog, its more serious purpose, as I understand it, is to rein in hyperbolic warnings of looming fascism.
So, back when the Nazis were rising to power, what (besides thuggery, of course) was used to shut up the anti-Nazis?
Steve Caldwell points out that my question has been anticipated previously.
