No one is telling you you need to do violence, though. No one in Lemmygrad or Hexbear believes that the time to take to the street and start shooting is right now, obviously it wouldn't achieve anything and would just be a waste of life, that's why fascists are the ones committing mass shootings. What we believe is that when the contradictions mount to the point that the ruling class clashes down on its opposition with violent force, we need to be organized and ready to carry out the revolution come hell or high water, like every single socialist revolution in the past. Whether or not you personally want to participate is irrelevant because the historical process in which capital undermines its own existence is inevitable, some amount of time from now the crisis of capitalism necessarily must reach a point where its contradictions can't be reconciled anymore and either the ruling classes succeed at preserving the system, or the workers succeed in transforming it into something new. Furthermore, regardless of your own participation in the violence necessary to maintain capitalism right now, that violence is happening anyway, and it's orders of magnitude larger than the violence that the left is capable of, even if we were the bloodthirsty maniacs some liberals claim us to be. The black book of communism claims that communism's death toll nears 100 million, but every 10 years far more than 100 million people die because of preventable illnesses, hunger, and conflict, which are all direct effects of the decaying economic system. If you reject to resist that system, then you're complicit too, even when so little is asked of you.

What about self-defense?

Is a person defending themselves from an attacker, morally wrong for using violence? And if you concede that it isn't, then what about workers banding together to defend themselves from the injustices of enforced poverty, starvation, homelessness, and war?

When is violence permissable or moral then? Absolutely never? You have to imagine the types of situations people in the world face. I know a person from Gaza who was nearly finished with his university studies, now he lives in a tent with his mother and his little sister is dead. When I'm able to talk with him, he expresses almost nothing but violence and hatred against the Israeli state and the IDF.

Are you saying my friend Ali is in a bubble he should get out of? Or are you simply talking about your own experiences? Because even if so, you should at least feel some inclination of rage towards the people who did this to my friend.

I'd go find some people who aren't so focused about gatekeeping who is "validly left".

OP seems to be the one doing that to themselves, though. "Validity" isn't really a thing, purity checking is nonsense. Marxists and Anarchists believe Revolution is necessary, sure, but don't generally advocate for random acts of terror or forcing a revolution into happening, ie a coup.
