You're probably better wording a post like this as "I myself wouldn't go out with a bat, knife or gun and aim to hunt down. I wouldn't do this as I'd lose my job, my family and probably face prison. If I didn't get killed in retaliation myself by the oppressors, or by the police/army coming in and disarming me by force.".
That's probably going to have people say okay, fair enough. Just dropping the "violence solves nothing" line with no context will just antagonise people like why you've been quoted 20x times in short succession. If the extremists were to start on mass, shooting, attacking and killing the police (or more like the army) would respond with lethal action which is... a form of violence! Sure, the aim is to try and have it not escalate to that, so that there isn't mass bloodshed (especially civilian on civilian bloodshed), but as I spoke about earlier America is currently failing to handle its problems with extremism via discourse, de-radicalising and state enforced action (arrests/confiscation/jail/community service/restrictions on liberties/watchlists/etc).
When a terrorist attack happens in the UK we don't have lots of people saying they'll be taking to the streets to attack/hurt others because civilian violence is the way forward. I mean if you said something with the intent to be violent on social media in the UK you'd probably have the police arrest you. What we do have though is a government who has radical watch lists, monitoring, arrests for extremist preaching/calls for violence and so on. All of that helps the public believe they are safe. Or at least it lets the public think the Government is at least making an effort to tackle extremism and to keep people safe.
So yeah, to me it can be a bit jarring when tens if not hundreds of posts across multiple topics are calling for civilian enforced violence. The UK isn't the US though, and a lot of unrest in America is happening because the Government is failing the people. Even our Conservative government as much as I criticize them does at least say a lot of the right things around terrorism, and you wouldn't be seeing neo-Nazis walking around with assault rifles in the UK. Ever. In America you currently are! A lot of people on forums are just blowing off steam too, and usually, it's quite clear to see when that is the case. As it's often quite clear too when people are talking about violence in general (lots of WW2 posts), rather than "I myself am going to be violent". Even in America with the later, you have to be careful as intent to cause harm/violence is just about the only thing not covered under the 1st amendment.
