> However, once you actively get in the way of official federal policing business, you are no longer a peaceful protester.

That is absolute nonsense. You can be a peaceful protestor whilst still inconveniencing the authorities.

Possibly the most famous non-violent protestor of all time is the unnamed man who stood in front of a column of tanks at Tiananmen Square.

Another contender would be Gandhi, who promoted civil disobedience for peaceful protesting.
