You site is too busy and preaches - no it goes a bit beyond preaching. You are basically calling the viewer an idiot by restating the obvious. Over and over. I seriously doubt there is an adult using the web who hasn`t heard it all before, let alone a parent.
If parents are going to try to shield their kids from the world, you won`t need to preach to them to buy your product. They are already on board and don`t need convincing. Just keep the site simple, use more headers, and sell the product, not the fear.
A screen shot of the browser would probably help.
