Hamas affirms that its conflict is with the Zionist project not with the Jews because of their religion. Hamas does not wage a struggle against the Jews because they are Jewish but wages a struggle against the Zionists who occupy Palestine. Yet, it is the Zionists who constantly identify Judaism and the Jews with their own colonial project and illegal entity. Hamas rejects the persecution of any human being or the undermining of his or her rights on nationalist, religious or sectarian grounds.

Note that Hamas is not the only Palestinian faction, but as the one everyone sees fighting Israel, the other factions, and the people of Gaza support them. When the people of Palestine are no longer fighting for their existence, I have no doubt they will support more secular factions as they did before.
