Reagan had a 20+ year record of conservatism before running for president - supporting candidates, promoting it via speeches and op-eds, as Governor of California (no, he wasn't perfect, but saved the state from the first Gov. Brown), etc. So that is a very imperfect comparison to make.
Reagan had the same popular reaction, that is my point.
If we can’t differentiate the reasons morally for Hitler VS what is happening now, then there is no hope.
Comparing Trump to the rise of Hitler is not only historically stupid, it is a sign of absolute desperation.
