I think that schools should not teach whether or not Santa is real. I think you can read a poem, and have it be a poem. If a child asks if it is real, then a teacher should tell the children that they should talk to their parents.
I think that sex-ed should be handle in much the same way. In that, when children are old enought (junior high, high school, then the children need to be taught the biology of sex. As for what is right or wrong, that should be left up the parents.
Sorry for all the errors in the previous post.
Here is the corrected version:
In that, when children are old enough (junior high or high school) then the children need to be taught the biology of sex. As for what is right or wrong, that should be left up to the parents.
