Hamas is not an "Islamist" organisation (I hate that word BTW, as it's an Israeli invention to demonise Muslims).
The article you linked to is pure propaganda - Hamas' charter changed a long, long time ago. OTOH, Israeli politicians literally say genocidal things on a near daily basis - it's a deeply sick society.
