I reject that argument because it is a Jewish state, founded in the wake of the holocaust, attacked for being Jewish in the first days of its creation. For better or worse, It is inseparable. In fact, if you go to Palestine, they do not speak of "Israelis" but of "Jews". Spilling Jewish blood, killing Jews, a curse upon the Jews, etc. You see this with hate crime on synagogues and Jewish homes, Jewish individuals, business world wide a response to what happened in Israel and Palastine.
If your enemies do not make such a distinction, then why should you? It only obscures and confuses what is pretty clear.
