It is untrue, absurd, and painful for anyone to argue that those who formulate a criticism of the State of Israel is anti-Semitic or, if Jewish, self-hating. Such charges seek to demonize the person who is articulating a critical point of view and so disqualify the viewpoint in advance. It is a silencing tactic: this person is unspeakable, and whatever they speak is to be dismissed in advance or twisted in such a way that it negates the validity of the act of speech. The charge refuses to consider the view, debate its validity, consider its forms of evidence, and derive a sound conclusion on the basis of listening to reason. The charge is not only an attack on persons who hold views that some find objectionable, but it is an attack on reasonable exchange, on the very possibility of listening and speaking in a context where one might actually consider what another has to say.
