Bernard Lewis is Jewish himself and has been attacked in the past by the likes of Edward Said and Noam Chomsky. He is now 96 years old.
And your point is? Lewis wrote what he wrote and it is ignorant, dangerous, and fundamentally inaccurate (historically and religiously). His so called expert opinions lead to death for all non-muslims——and that would include all of the Jewish faith as well.
Lewis has been even-handed when dealing with islam culturally ("What Went Wrong?")
When dealing with its religious dimension, not so much. Perhaps he deluded himself that the cultural, religious and military facets of islam were seperable. After investing a lifetime in its cultural pursuit, denial and perhaps political correctness is unavoidable. He can't contemplate that the negatives of the islamofascist far outweighs its contributions to modern civilization.
If he doesn't consider his life a waste, he should.
