LOL! So we should forgo teaching anything that might offend anyone in the school, even if they themselves don't take the offending course, for fear we contaminate the 'culture.'

Solution: Begin the process of privatizing universal K-12 education. Parents, teachers, and principals, in private setting, should be the people deciding how the origins of life be presented to the children.
Better solution. You, the Islamists, the sexual harassment industry, and the rest of your easily offended brethren learn to deal with it. There is no right not to be offended, and privatizing public institutions simply because of a few soreheads makes no sense at all.
