The problem with you hyperventilating about this as a supposed rebuttal to me is I agree with every word of it.
Let's disentangle this from US politics and maybe you'll be able to step back from the edge a bit. The point is that Likud has always wrapped itself in the blue hexagram and cries that ANYBODY -- domestic or foreign, Jew or gentile -- who calls them on their murderous BS is an anti-Semitic surrender monkey who wants to see the Hidden Imam dancing on the glowing nuked remains of Tel Aviv.
That card gets played so hard and so often it was already a thoroughly discredited rhetorical strategy in the 80s. We'll ignore its effect on US politicians and political debates and just concentrate on its (lack of) merit. It's a way for the right in Israel to mobilize their extremist supporters and demonize anyone who might even in principle partially object to their settlement / ghettoization strategy. Plenty of Israelis loathe them for it -- even plenty of Israeli Jews. Telling Bibi there are limits to the US putting up with his constant ratcheting up of rhetoric and violence in no way backs off from the US commitment to an alliance with Israel. It just underlines the simple fact of international diplomacy that in a defensive alliance between X and Y, X is not necessarily obligated to help Y if they haul off and attack Z.
