Actually the number is 93% BLM protests considered peaceful. And even in the small number where violence occurred, not every participant that was in a protest that was violent participated in the violence themselves. So the number of people that would be considered problematic is extremely small.
And don't forget what I mentioned before...
At least some of the cases where violence and/or looting occurred, those involved were not part of the BLM protests, but were merely using the protests as cover for their crimes. In other cases, it was right-wing agitators who were causing the problems.
Compare that to the Truckers rally, where pretty much 100% of the protests have caused problems, and here in Ottawa it appears that pretty much 100% of the troublemakers have actually been associated with the rally.
And the organizers are racist cranks, a fact that all the "oh it's just a few bad apples" folks keep ignoring even though it's kind of a big deal and certainly enables one to make some judgements on the kind of followers such individuals would cultivate.
