Absolutely.

Violence does solve things, but also can make for an immediate 'Very Bad Time'.

Police use violence. Military uses violence. Difference is state-monopoly or not. To say violence doesn't work would be to say the police and military don't work - and they do.

Anybody calling on violent means should absolutely call upon peaceful means first, secondly, and more. Violence should only be after all peaceful means have been tried.

Its better to win by peaceful means, than by exertion of violence. And, violence is no guarantee of winning. And even if you do win, can still be pyrric, in which everyone loses.

Tl; dr. Be wary of people casually calling for violence. They're either a state actor, dumb, or both.

That's why Donald Trump's electoral victory stopped a violent revolution
