When Hamas talks about obliterating Israel, they mean the government, not the people. They have not mentioned genocide. Palestinians (Muslims and Jews) should live together peacefully, side by side, and the governments should stop creating issues that separate the Semetic people of the Middle East.
There is a great deal of difference between a government and its people. The people voted for Hamas but Hamas is not the Palestian people anymore than Bush is the American people or Israel is the Jewish people.
