“Just read the debate of the Ramban. I don’t think they got any new material since then.”
There weren’t any fundamentalist protestants in the Ramban’s days. You actually have to speak to them differently than to catholics. One reason is that their attitudes — all of which are sheker ve’kazav anyway — toward the Tanach (“the Bible”) are not the same. One of the first questions I ask in a debate of this sort is what denomination they belong to. Rabbi Singer is superb. If you are for guidance in this field, he is definitely worth listening to.
