This is not true.

There are plenty of people horrified with both Israel and Hamas, and that while sympathizing with the plight of the Palestinians, think Hamas is hurting their chances of a peaceful solution.

Many people think Israel's right-wing and Hamas need each other, a kind of symbiosis. (Netanyahu certainly needs Hamas to exist).

Of course, the Israeli right wing wants to paint any opposition as pro Hamas anti semites. It's a time tested tactic.
