First, nobody proposes boycotting �E�Y�; they propose boycott the Zionist State of Israel.
They are exactly the same thing. The state of Israel is located in Eretz Yisroel. And the boycott is of any Jew living there.
As I wrote before, there is no such thing as an anti-zionist who is not an antisemite, unless his opposition is based on one of the three grounds I listed. And all three grounds make it impossible to support the “Palestinian” cause either. So anyone who supports a “State of Palestine” but opposes the State of Israel is an antisemite. It should surprise nobody that there exist antisemites born to Jewish mothers, with Jewish neshomos, just as there exist Jews who are murderers and all kinds of other terrible things.
