To call Rabin a Nazi and a traitor is equally horrendous. This in turn further radicalized the left, which in turn further radicalized the right. Words have incalculable power. The Rabbis teach that embarrassing someone in public is the equivalent of murdering him. Some thirty six biblical laws relate to the uses of language, by the count of the Hafetz Haim.
Rhetoric creates reality.
It is to respond to the Rabbi or to Rabin, persons with deep convictions of their own, not as a human being who is wrong, but as an avatar of the devil himself. Inflammatory slogans prevent dialogue, discussion, persuasion. It is to prevent self- criticism. To sling slogans is the refuge of the insecure. It makes you feel good.
