Dear Rabbi: I read with great interest the account of your sermon on “Exploitation” in Sunday’s Times. My reaction to your blast follows: First of all, I doubt very much if you are engendering any good will, so much needed, between Christians and Jews. Kaufman displayed bad taste again. Do you know his reputation? It’s not much admired for his personal conduct. On TV, his “comic” was of the first magnitude and, in my judgment, can be hoping to make it bigger still. Do you think I’m joking? Test yourself. You will get many letters pro and con. Separate the Christians out from the Jews! And then judge. Be honest! You will see that this is a Jewish viewpoint.
