Hamas are an Islamist group - but they didn't start that way. Initially, they were a charity and were supported by the government of Israel. They have changed drastically over the decades since their formation in the late 80s, due to continued oppression.
The PA are Israel's lapdogs and have no legitimacy in the eyes of the Palestinian people.
The overwhelming majority of Palestinians prior to the war hated Hamas, and there were protests against this regime in the months prior to the war. Just over 50% of Palestinians wanted a permanent ceasefire with Israel and to have 2 states on the pre 1967 war borders.
This is not a religious conflict. This is about land theft, justice, the denial of basic human rights, apartheid, oppression, murder, massacres, dispossession and racism.
