2. Mike Godwin himself says that comparing Trump to Hitler is justifiable. https://www.washingtonpost.com/posteverything/wp/2015/12/14/...
3. Usually when I see comparisons of Trump to Hitler, and discussions of whether that comparison is defensible, there's rarely any discussion of how the "present day" changes anything. Godwin does make the point that in 2015, we now have the capability to question poor arguments more effectively. But I've seen basically no arguments that the world is fundamentally different from the past, just that Trump is a fundamentally different demagogue from those we've seen since 1946.
