That's what supporting Israel results in.

That is, in part, the product of AIPAC. I don't see how they can deny that.

If you "Stand with Israel" that is what you are standing with.

Let us recall: Israel is the Jewish state. Can anyone deny that?

Ben-Givr is a duly elected authority of that state. Thus Jews, to the extent they stand with Israel, must accept responsibility for what Ben-Givr said.
