Oh for goodness' sake, it is a World History course. I don't see anything wrong with the curriculum and the overly dramatic parents will likely lose this battle in court.
So teach the history of Islam...but don't you dare try to teach prayers or conversions, if you do then the Rosary and any religious prayer/conversion must be taught
I like the idea of forcing muslim kids to memorize the rosary prayers-----come
up with a SCHOOL set of rosary beads and do GROUP rosary recitations as
a HISTORY LESSON. I like the idea of every classroom including a
life-size statue of BUDDHA -------and all the kids be required to do the
rituals that Buddhists do----when around those statues
