Charlatan

The main reason, that I see, for not allowing a religious teacher access to teach a lesson on world religions is their tendency to proselytize. I certainly wouldn't be happy if an attempt was made to draw my children into a religion. This is doubly true when I am in a minority.

I can only imagine the opposite to be true as well.

You would have to be able to hire some very sound teachers to teach a course on world religions. They would have to be very diplomatic and would ultimately be open to slings and arrows from every direction (e.g. Which brand of Christianity are you going to explore?).
