It's not anti-Semitism, it's anti-Zionism is the usual refrain of the anti-Israel left. Even when they're claiming there's a vast conspiracy that controls all the banks and foreign policy while selling organs, it's okay because they're saying, "Zionists", not "Jews". And now they're trying to apply that same strategy to Hamas. That would seem tricky as Hamas is pretty open about its genocidal anti-Semitism.
Just look at the Hamas charter.
"This Covenant of the Islamic Resistance Movement (HAMAS), clarifies its picture, reveals its identity, outlines its stand, explains its aims, speaks about its hopes, and calls for its support, adoption and joining its ranks. Our struggle against the Jews is very great and very serious"
"The Day of Judgement will not come about until Moslems fight the Jews (killing the Jews), when the Jew will hide behind stones and trees. The stones and trees will say O Moslems, O Abdulla, there is a Jew behind me, come and kill him. Only the Gharkad tree, (evidently a certain kind of tree) would not do that because it is one of the trees of the Jews." (related by al-Bukhari and Moslem).
"Israel, Judaism and Jews challenge Islam and the Moslem people. "May the cowards never sleep."
This isn't subtle stuff. But it's okay if you change Jews to Zionists. Which is what's being taught in Newton, MA, as Americans for Peace and Tolerance reveals in this video.
Additionally...
Newton's schools presented students with a falsified version of the Hamas Charter. In Newton's doctored version the word "Jews"– as a target of hatred -- is replaced with the word "Zionists."
In one lesson, Newton students are asked to consider the Jewish state's right to exist. (The legitimacy of no other nation-state's existence is questioned.) The lesson included "expert" opinions, which are drawn overwhelmingly from anti-Israel academics and anti-Semitic activists.
A book used in Newton high schools has a recommended reading list that includes the extremist writings by Muslim Brotherhood leaders including Sayyid Qutb, and Yusuf Qaradawi, whose sermons call for the murder of Jews and homosexuals.
Not to mention their view of America and Islamic terrorism is none too sunny.
