Hamas is only one of many resistance groups in Gaza. And the ideologies range massively from far left to far right. It's how they're able to sustain a prolonged resistance against Israel's constant aggression.

Focusing on Hamas's leadership - they have been mostly centrist and advocate for equal rights of all, with outliers that are more right wing and Israel repeatedly kills off the moderates in the party for a reason. Israel wants the hardwingers to be more prominent. Israel even wanted to bring back Ahmedenijad as president of Iran and that guy is the poster child of "death to the infidels".

You're also equating Palestinians with Hamas too, don't do that.
