In 1948, during the Nakba, Israel ethnically cleansed much of Palestine. From that (and a good portion of the ethnic cleansing Israel has done since), many of the people were driven into Gaza.
In 2006, when Israel got kicked out of Gaza due to an uprising, they built a wall around it and restricted the amount of food, fuel, and other items, and banned the gazans from constructing wells, water containers, and other things that would allow the people in Gaza to stay alive longer if Israel cut off food/water supplies.
Fighting against settler colonists who came and established an apartheid regime is not a crime.
Israel is a settler colonial project, an Israel that provided equal rights to all Muslims, Christians, and Jews living in its territory would be less related to the current state of Israel than modern South Africa is to Apartheid South Africa.
Yes, we agree that it’s antisemitic as fuck to associate Jewishness with Zionism. When Israel is murdering children in public view, implying that Israel represents Jews is just blood libel with extra steps.
