I'm confused what you mean by that AA.
If you mean support for the establishment of a Palestinian state ('Land for Peace'), that is basically a Centrist philosophy, indeed a majority opinion worlfwide and within the US. That is not the preserve of the Far Left at all, although large elements of the Far right are resolutely opposed to it.
If you mean the elimination of the Jewish state, well that is a lunatic fringe philosophy shared by some fringe groups on the Far Left, Far Right, and some Fundamantalist, Messianic Jews.
Either way, I'm still uncertain how that fits into SF values- unless you are referring to the fact that 'Queers for Palestine' or whoever are allowed to hold a public rally there. Unless I'm very mistaken however, the 'for Palestine' is referring to the establishment of a Palestinian state- not the destruction of the state of Israel.
