By all means, Muslim class like that would work as well. Given that the US is majorly Christian country though, Christian class like this would have more effect.
Muslim class like this in Iran, Saudi Arabia, etc. would be very effective.
Once again, being respectful towards the people doesn't mean doing only things they are okay with. If the teacher talks about evolution, should he be altering his narrative out of respect to those in class who believe in creationism and are offended by what they see as blasphemy? The teacher's job is to get kids thinking, and it is only done effectively when kids are forced to question their deepest beliefs.
