The average person, particularly those with "progressive" mindsets borne of media brainwashing and disinformation, literally have no idea how horrible Trudeau is, nor how horrible Obama was.
They also have no idea that they've been brainwashed to hate Trump based on nothing but progressive big lies and hate campaigning by the Left's corporate, controlled media wing.
They are of the same sort of ignorant, gullible, manipulable mindset as the People of Germany were when they mistakenly voted for the Nazis.
So no wonder they're insane-due-to-acquired-falsehoods-which-they-believe-without-question. Such fools refuse to think independently and insanely trust the Left's corporate, controlled media unconditionally. This is dangerous. This makes them into controlled-voters-for-danger.
