We do teach about karma, in world history, but not as fact. I also remember hearing about many different types of creation stories, including genesis, in literature classes. It's a complicated issue, I don' tknow that there is a right answer for everyone, because your point is exactly right valkyrie, in the sense that I dont' want every crazy theory known to man taught to my children as fact.

For example: A big issue is prayer in schools. I am a Christian and don't think that it should be allowed because I don't want a toaster worshipper leading my child in some butter and jelly prayer to the knife god. I dont' want a Satan worshipper teacher telling my kid about their religion. This was part of my point in character education....I don't want a teacher telling my children that accepting certain lifestyles or behaviors are ok. I am one that will probably send my kids to private school so I won't have to worry about this issue. NO I don't think Creationism should be taught in schools, but I don't like the other theories either. Maybe they can just skip that part of science class.
