My guess is it would have something to do with Ann's call to forcibly convert all Muslims to Christianity. Its a quick step from that to converting the Jews. I understand their reluctance.
I don't.
Given the very weak (if at all) interest in proselytizing among Jews (whose Jewish identity passes through the mother, if I'm not mistaken)... you would think they would be delighted if Christianity would convert Islam to the Judeo-Christian sensibility and thereby disabuse many of the mistruths which have allowed militant atheists to pretend they are "radical Islamic fundamentalists" when -- in fact -- they've nothing to do with faithful Muslims.
It's an interesting question, really.
