While I agree that the US is becoming a "turn-key totalitarian state" it is patently absurd to compare Sanders' brand of social democracy (an ideology incredibly far from Socialism) with Trump's fascism.

Social democracy coexists with Western values in basically the entirety of Europe. It has not led to the collapse of the continent into some totalitarian nightmare.

The fascism being advocated by Trump and members of the alt-right however draws a lot of comparisons to the rise of the Nazi party in Germany, and not because the right is unpopular with academics or journalists but because Trump and his supporters are using violent and xenophobic/racist language while they scapegoat ethnic and religious out-groups.
