One caller asked about Bernard Lewis. The guest smirked and said that Lewis isn't held in high regard in academic circles.

Right. Dr Bernard Lewis, Professor Emeritus of Near Eastern Studies at Princeton University. He's pnly been studying, teaching, writing about this for 50+ years so what could he possibly know about it.
Could it be that the "guest" is a little envious?

I think the speaker was an internationalist/multiculturalist who found Prof. Lewis' attitudes about Islam unforgiving. After all, we should be able to settle everything around a table, right?
