IMO violence is a spectrum. Peaceful protesting with signs is 0 violence. Attacking self-driving cars or department stores without hurting any people is a bit higher up the scale. Attacking food supplies or critical infrastructure is higher still, as it will have downstream effects on everyone that might lead to death and suffering. Attacking actual human bodies is even higher up the scale of course.

I get your point though. There's a strong push to characterize destruction of property as violence, as part of a push to delegitimize protest. To some people, the police can use physical violence against people to stop a protest and that's okay, whereas if the protestors so much as throw a brick through a window, they're violent extremists.

When it's -30c outside and your house hasn't had heating for days, you might disagree.
