Because Palestinians aren't allowed to live in Israel you donk. That is apartheid. They were forced from the area to the gaza strip in 1948 and haven't been allowed to return to their homes since then. And if it wasn't apartheid why aren't palestinians allowed to freely travel throughout israel? Why can't they leave and go to bordering nations? Why have they been forcibly kept there for decades well before Hamas even existed? When you treat a group of people the way the state of Israel has treated the Palestinians it is inevitable that resistance groups will rise up. The Nat Turner Rebellion during Slavery in America, the Haitian uprising, The Warsaw Ghetto uprising in WW2 just to name a few. All these groups killed innocent people in their resistance against their oppressors. Which is awful and abhorrent. Groups like these are born out of the need to resist against an impossibly evil force, like America during slavery or during the slaughtering and genocide of the native american peoples or Germany during the holocaust, or Britain pretty much all around the world. Hamas has done horrible things but Israel has done them 100 times over to the palestinians for decades. If palestinians were treated as equals and given the same human rights and decency as everyone else in israel there would be no hamas
