I think the trucker protest was unique (and different from OWS, BLM) due to it deliberately targeting ordinary, unrelated citizens instead of the government. It would have been more like other protests if they blockaded and blew their horns at Trudeau's front lawn or Parliament or Big Business or something, but instead the protesters specifically went after the wellbeing of ordinary Canadians. All protests "involve discomfort" to normal people, but this one uniquely targeted them.
EDIT: This is not letting individual BLM protestors (who did deliberately target private businesses) off the hook, but the movement itself did not specifically call for belligerence against unrelated citizens.
