You're presenting a selective history.
And yes, although the Israeli army has plenty of war criminals that should be sent to The Hague along with Netanyahu for their actions in Palestine, Lebanon, and Syria, Hamas was never justified in kidnapping Israeli citizens in the first place. Terrorism is never justified, and terrorists on both sides deserve to be tried for their war crimes, as should be the case in any war.
I suspect that is why you were banned. Nothing about Trump. People like to do this, present one complimentary fact about their case and pretend that innocent thing was the whole reason for the response, instead of the less complimentary things they also did.
You are not by any means wrong in that statement. Hamas has no right to kill, rape, and kidnap a bunch of young Israeli civilians who have nothing to do with the occupation except having happened to be born in a country whose government is committing atrocities, and no amount of war crimes by the IDF would give them that right. However, I will have to say that trying to say that true fact in a Palestine community specifically, is probably a tactical error, and will lead to no good outcome and often to a ban.
PTB, I guess, technically, but asking people whose family members are being killed to sit still while you to tell them their side is also the bad guys is quite a lot to ask.
If it were me, I would focus more specifically on the fact that letting Trump get elected has now absolutely doomed everyone in Gaza and quite a lot of people in the West Bank. With Biden it was already a genocide. Under Trump, it's now going to be an accelerated genocide, with much grander scope and ambition.
