There is a mighty large difference between a sit-in and a riot.

True, although a sit-in is not necessarily entirely benign, pure and devoid of consequence.  A sit-in can cause institutions and commerce to grind to a halt, inconveniencing and disenfranchising many innocent people.

Legal channels of redress typically don't shut down universities and businesses.
