What exactly are they protesting? Bill Clinton had connections to China regarding campaign contributions and no one blinked.
Even if popular unrest exploded, the fact that the majority of anti-Trump protestors lack weapons (anti-gun), are urban (will suffer when the power is cut, the funds and trade halt, and the food runs out being encircled), and that the military and police are behind executive authority, I see protests dying out in no more than a year. This isn't Red Dawn where rural forces suited to guerilla action are battling for freedom. Protests would play right into Trump's hands allowing him to crush the Left. Americans, especially Trump supporters, hate traitors.
You want a successful revolution you need the desperation of the Depression before Communism and Fascism was discredited.
