Oh, that's an interesting story. I have discovered the true nature of islam in the 90ies. I was participating in this list-serv on philosophical anthropology, and there was one participant who was a scholar of islam for many years. He even learned arabic. He was a history professor, as far as I remember, not a professor of islam. So he studies islam for himself. It wasn't his profession. But because he was a very scholarly, academic man, he learned it very fundamentally and read the whole Koran in arabic. So one day, somebody said something ignorant about islam, and this man set him straight. This was a real eyeopener to me. This is when I learned about dar al islam, jihad, dhimmi, taqiya, and also the principle of supercession. Whatever is written later supercedes the earlier meaning. So the militant later verses from Medina take precedence over the milder earlier verses from Mecca.
