No, I do not think that exposing kids to porn is a good idea. I do not think exposing kids to John Kerry is a good idea. I can not prevent them from being exposed to Kerry and I can not prevent them from being exposed to porn. What I can do is to try to teach them that John Kerry and porn represent something that is against our family values. After I have made my best effort, the rest is in the hands of God (not you).
"I can not prevent them from being exposed to porn."
Why not? Society prevented children of my generation from being exposed to porn.
