If you scroll through the community bans of World News@lemmy.ml, you'll see there's a mod going crazy handing out months long bans for having the wrong opinion on the current conflict. Mods aren't beholden to anyone but themselves, so if that's how they want to mod then that's how it's going to be. Thankfully, Lemmy has hundreds of communities discussing the conflict so you might find better mods in one of those communities.

If it makes you feel better. I also reserve judgement until more information is out. The counter arguments as to why it wouldn't be Israel does make sense to me. Lack of crater. Hospital walls intact. Hamas were firing rockets over the hospital. And the death figure is reported by Hamas. Most likely incredibly inflated.

Since when was recognized terror organisations reliable sources?

Join an instance you believe in. If it happens to enough people they will move on.

I'm really sorry for what happened to you. And I'm really disappointed because lemmy allows fascist instances and fascist friendly instances to stay, like lemmy.ml, the bears, the grads, and others. Why can't they just leave like exploding-heads did? Why right fascism is bad and left fascism is good, when fascism is fascism after all?

Lemmy isn't a place for debates and arguments. If you don't follow the direction of the topic, don't bother inserting yourself into the conversation.
You need to be nice and supportive of whatever is posted, else you're going to have a bad time.

Read their code of conduct and you'll find that it's a moderator's discretion to ban anyone they believe is disruptive, regardless of the rules.
So unless a moderator goes on a deranged banning binge, you're automatically in the wrong.
If you can't accept that, i suggest you make your own instance, with blackjack and hookers.
