Here in Missouri the 6th-grade world geography/history text did cover the major religions—Judaism, Hinduism, Buddhism, Christianity, and Islam and the major tenets of each. So, I covered Islam as well. But I had to explain that “jihad” meant a bit more than just the struggle to “get right with allah” and that despite what their textbook said, women were treated little better than dirt in the really “pious” Islamic nations. I tried not to lie to my students.
Did you mention Islam's role in the North and South American slave trade?
Seriously, this is how people should be informed about Islam. Islam is responsible for the bloody US Civil War. Islam ran the slave markets in Africa.
