Yes, I am familiar with Sen. There is merit to what Sen says and there is merit to what Huntington has said. I am not an absolutist - I don't believe any one theory on this subject is entirely right or entirely wrong. Also, what David Duke things of Huntington does not influence what I think of Huntington. I judge him by his work and I dont agree with him on everything. But I read that book and while I dont agree with every sentence and observation he makes, like I said before, he indirectly seems to give credence to the fact that all major civilizations are capable to. That's my take away from the book. And I think it's a fair one.
