Abbott's comments don't have anything to do with Zionism, though. Regardless of whether you're Irish (Traveller or not), Jewish, or a redhead, the message is at best highly tactless.
Because of the history of interactions, Zionists might be especially eager to take her down a notch, but the message was ill-conceived completely without reference to Zionism.
