When the rich break the social contract.

When someone who I was supposed to be able to trust kept repeatedly trying to record me naked in the shower, I retaliated once by kicking him hard in the face. I was told that what I did was wrong and violence was never the answer. I disagree.

Punching nazis. Always acceptable, even encouraged.

Nobody else has mentioned proportionality.

When responding to aggression, the response should not significantly escalate the risk. So lethal force should only be applied in scenarios where there is a lethal threat, etc.

Violence is justified when it’s needed to protect yourself or someone else from violence. That’s about it, honestly.

I am not a fan of pre-emptive violence.

Self defense, as part of a game (such as wrestling) or in BDSM, when both sides are okay with it and don't face actual danger.

Self défense, yep. On a battlefield ? Let these old fuck fight one vs one to resolve their conflict. A noble end is so fucking subjective that I think it would be a terrible idea.

Violence is justified when you have no other means left to defend yourself or someone else otherwise.

At which point I would like to add that people will sometimes not be able to see the means they have left because they are put in a stressful situation in a second. I feel like you can't really blame them for that.

Violence as a response should always be in proportion. That should avoid escalation. In an ideal world.

Unfortunately some people won't stop. Those people need to be put into prison where they cannot hurt anyone anymore.

Use of some violence is justified to stop another bigger, ongoing violence.

I heard a quote that has really stuck with me, it goes something like "violence is the supreme authority from which all other authority is derived"

I don't really condone violence, but this quote has really gotten me thinking.

When you are the victim of a loot ninja

Much more often than I actually do it.

To protect against violence

when someone is WRONG on the internet

Yes.

Self defense

Violence is a form of escalation. One should never cause a conflict to come to a new height and should only resort to something if in response to anything of that same height.

Also, if a ruler of a nation resorts to that, it shows they're not a great/effective ruler. Fluency in how to rule is determined by how much peace you can accomplish with as little change as possible. Less is more, as they say. If you have to punish people too often like some are doing, you're violating that "less is more" rule.

Self defense but also including defending your rights, freedom, property, and sovereignty

Only when all other options are ruled out. And obviously, you should not be the aggressor in any situation

It's always a matter of degrees. The bigger the injustice, the more violence is justified to rectify it. It is in the disproportionality, in my view, where the problem arises.

Never forget that humans are just barely evolved apes. Sometimes a swift knock to the head is required to activate those neural pathways to discourage anti-social behavior. Not always, but also not never. Claiming otherwise is just self-aggrandizing moralization that people use to make themselves sound and feel superior.
