- dealt with harshly -> torture and summary executions. Tied with a rope to a car and dragged through the streets. Thrown from a rooftop of a tall building. That sort of stuff.
- "Suspected collaboration with the occupier" -> being associated with the Fatah, PA, or just not doing what Hamas orders you to do in any civil or other matter. Basically any person that crosses Hamas members in any way. Think Mexican drug cartels hanging journalists from bridges and you won't be far off.
- occupation -> the existence of the state of Israel in any borders. occupier -> Israel.
- Gaza's occupation -> The blockade Israel imposed after Hamas took over Gaza by force and started launching attacks at Israel from Gaza. Please ignore the border with Egypt or Egypt's control over the Egyptian half of Rafah. Egypt doesn't exist. Waiting for the Muslim Brotherhood to take over there but in the meantime let's support ISIS in Sinai since an enemies enemy is my friend.
- "Israel routinely cuts water supply to the Gaza strip" -> Israel supplies water, food, electricity to what is essentially an enemy state that attacks it continuously. Gaza has its own power station, it has a desalination plant, it has wells, and it can also get all these things from Egypt or use the international aid money it's getting towards becoming more independent. Nah- let's dig tunnels and build rockets. Think Ukraine supplying Russia with water, food and electricity. Or South Korea supplying North Korea.
You are right that Hamas would win an election. Even more so after Oct 7th. The Pro-Palestinian crowd does its best to pretend it ain't so. They artificially separate Hamas, who the Palestinians want to represent them, from the Palestinians. Palestinians are peace loving people that need to be protected at all costs and the Hamas are people from another planet that just happened to have landed in the midst. There hasn't been an elections since 2006 so Hamas is not the legitimate government of Gaza and so we can't treat the Gazans as a side to this war. Even Israel says the same thing, our war is not with the "Palestinians" our war is with Hamas.
