The idea that we don't teach certain aspects of subjects because it might offend people is just going to breed ignorance.
Some people don't believe the holocaust happened, we still need to teach it. Some people don't believe evolution happened, we still need to teach it. Ignore facts because they go against peoples beliefs is outrageous.
Offended is your word. Nobody here or myself suggested that. Holocaust has so much evidence and footage its a no brainer and not the best comparison.
