Boogaloo Boys do not consist of 80 million US citizens. They're a fringe group trying to be a militia. HK citizens were violent because their voices were not heard, they're not a militia, nor are they fighting to oppress and upend democracy, they're fighting for the exact opposite.
You can see in video after video that they're mostly young people (20s), and their message was "burn with us" [1]. Carrie Lam withdrew the bill and that still wasn't enough for them. Realistically, they were never going to get the 5 demands met, and it was clear they wanted to incite police violence.
There were plenty of people, especially those who were a bit older and those who owned small businesses who wished they would go away, and the national security law has guaranteed that. I know HK culture is quite separate from Mainland culture in quite a few aspects, but I can't see how any of the violence has helped.
And only in one of those cities were there gasoline bombs thrown on the street.
