Why do many Leftists fervently believe Trump is a reincarnation of Hitler?

One of the laws of online discussions is that the longer it goes, eventually someone will make a comparison involving Nazis or Hilter (https://en.wikipedia.org/wiki/Godwin%27s_law). This seems most accurate when Leftists think about Trump... an example from the NYTimes today: [nytimes.com]

While it is true that Trump has a reputation for invoking patriotism, it is unclear if his actions as president is a "lurch toward authoritarianism". In the 1930s, Hitler moved to censor the press, organized boycotts of businesses run by those he didn't like, created a state religion of hate towards what he claimed were an oppressive group, tightly controlled arts (films had to have ideological messaging) and education (e.g., school age books to Indoctrinate hate towards a group), and promoted a chosen group as morally superior to the oppressive group. Could it be argued that these actions are more what we're seeing from the Left?
