Hamas is an extremist group, they are only considered a reasonable thing to support because Palestinians do not have human rights and are confined to ghettos. One party in this situation is actively genociding the other, and quite understandably Palestinians are more inclined to listen to extremists than the Israeli state genociding them. Israel has actively sabotaged every single attempt at negotiations since the mid 90s. Netanyahu can be thanked for that. Him and the racists who support him.
Hamas is nothing if Palestinians had rights. Palestinians are just people, they are not an army they are not a militia. They deserve human rights. Israel could do that today. They deserve their homes back. Israel could do that today. Hamas has nothing to do with it. There's never an excuse to deprive a race of people their rights and freedoms. Genocide is never acceptable. Apartheid is never acceptable.
