What abouit the thousand years of war between Islam and Christendom, most of which time Islam was on the offensive?
Supposed to ignore it ever happened. Remember: Islam is a Religion of Peace*
*No matter how many people are killed.
I'm presently working through a WebCT survey course on the World's Religions. It is rather well done.
In the Islamic section I was surprisingly surprised to listen to one of Islamic experts make the (to me) startling claim that all Islam's wars -- every single one of them -- were defensive wars. These acts of self defense included Mohammed's wars for supremacy against the Quraysh. Justification was simple, he said. Everyone has a right to self-defense.
To his credit, the interviewer caused the expert to squirm a good bit before moving on to the next topic.
