Jesus and Mohammad lived. Christianity and Islam exist. By not teaching that others may believe something different than what you do, knowledge is lost and then the first free thinking person will have hell to pay only because of intolerance. Knowledge is power. Beliefs exist, based in fact or not. not teaching that they exist leaves one unprepared for the future. I see nothing wrong in teaching what does exist, not so much what people believe. people should be free to believe in what they wish. Many would have us believe MMJ is just a myth. should the knowledge of "Mary Jane" be erased and pushed out of existence? The plant will still be a plant and people will still argue over its useful purposes. edit: i have attempted to format this post more than once. the wall of letters is not by design.
