I’m down as long as it’s presented in a comparative religions kind of way. If the guidelines don’t specifically say not to talk about other religions and/or nonreligious ideologies, make sure to throw in some material on Islam, pagan religions like Wicca, indigenous American religions, Hoodoo, Buddhism, etc.
And, as others have said, don’t just teach what casts Christianity or the Bible (or any of those other religions, for that matter) in a positive light. Talk about the KKK and abortion clinic bombings and the red scare and how bonkers the country went right after 9/11.
