Do you live in a metropolitan city in the US? Seattle, USA is my point of reference. I have lived for 15 years here, mostly living in the most dense neighborhood and mostly working in the downtown core.
Seattle is a low-violence, high-civic-engagement, high-trust, relatively wealthy city. There is typically a small 10-50 person protest weekly in front of the Federal Building. There will be additional larger protests several times annually, with a 200-500+ person gathering probably about every two months in favor of pot, anti-war, or whatever. Then 2-3 times a year there will be a large gathering, often around May Day, MLK Day, Hempfest, etc., where thousands will gather for (generally permitted and pre-planned) marching and demonstration. This is all the baseline activity level regardless of things like COVID, Trumpism, or BLM.
It's very usual to see strollers and children on shoulders at these events. The strong presumption is that civic engagement in Seattle is safe and normal.
If you come from a place where political parties have proxy street-fights with backed youth gangs, or where ethnic mobs are torching trains full of apostates, I understand (and I'm very sorry and hope it gets better). I know the world is a scary place and that there are such things as violent mobs.
But despite how inconvenient it might be to have one's commute path blocked, or how scary it might initially be to have an Other-looking youth shouting hyperbolic slogans, protests here (and elsewhere) generally don't start, and don't inevitably turn, violent.
That particular reaction requires another reagent altogether, and usually quite a bit of activation energy.
