I'm finishing up school & preparing for a career in education, & I'm usually viewed as liberal since I'm not a fan of Shrub.
I DO NOT SUPPORT THE PROPAGATION OF ANY RELIGION IN PUBLIC SCHOOL.
That being said, exposure to the tenants or ideas of different religions in the proper contextual situation is not only reasonable but should be expected in a well-rounded educational environment in free society. However, some of the earliest laws and regulations of this country speak about this very issue, freedom of religion, and they are rather detailed.
While the right to worship is preserved, as it should be, no other man shall be "compelled to frequent or support any religious worship". If Genesis is taught in public schools, then my tax dollars are supporting Christianity or Judaism. Is this freedom?
Witnessing or sharing ones testimony is a major tenant of Christianity, believed to be supported by scripture, and by many would be considered an aspect of worship since it so blatantly contains aspects of praise of a deity or exposition of belief with an intent to convert spectators or at least illicit reactions of guilt, fear, or obligation, not to mention the frequent use of peer pressure. I would liken this to many church sermons that I have attended in my uneducated youth.
If only I was allowed to taser Christians after being sufficiently irritated by their banter... hope springs eternal.
