I personally do not feel that barring adults from teaching religion to children is a violation of religious freedom, I do not think parents have the right to push their personal belief system on their children. Rather, parents have the responsibility to equip children with knowledge and skills to think and act critically. Parents do not have the right to enslave children, children are not the property of parents, and they are not their personal "spiritual minions" or servants.
I believe children are individuals but are vulnerable to intellectual manipulation, and religion is a very insidious and harmful form of manipulation. It harms children in their ability to reason and think clearly.
Therefore, religion, religious materials should be as pornography. I think its illegal to show pornography to children, and clearly its illegal to involve children in pornography, and I feel that religious teaching is at least equally as harmful.
That said, should the police be bursting into homes of families with children and confiscating any materials that could be deemed religious as they do with child pornography? Should parents who expose children to religion be treated the same as parents who expose their children to pornography, or worse, children who are coerced to become involved in teaching religion to others, is that the same as child pornography? Why or why not?
