There is certainly a wide range of opinions in the Jewish community on any number of issues (as an old adage goes, two Jews - three opinions). Tolerance—and fostering—of diverse views is a long-standing intellectual tradition of the Jewish people going all the way back to the Talmud, and it definitely includes varying positions on the Arab-Israeli conflict.
Having said that, I will also say that while the likes of JVP are in the news a lot lately with their loud “ceasefire now” protests—on college campuses and elsewhere—and their “not in my name” t-shirts, and although they are very vocal in siding with the likes of SJP, they do not represent anything close to the mainstream of Jewish opinion in America, Israel, or anywhere, and I would go as far as to suggest, nay, insist, that centering their position as if they somehow speak in the name of, or represent any sort of a moral authority for, a significant portion of the Jewish community is nothing short of tokenism.
This is Haaretz—a left-wing Israeli newspaper—in 2017:
“To many mainstream, moderate and even left-wing groups – and certainly for the Israeli government – JVP is beyond the pale, aiding and abetting those who would harm, or even eliminate, Israel if it were possible.”
