From the OP: If we have a TV, we’ll be able to overlook what, if at all our kids our watching. However, if we dont have one, there’s always situations where children ‘sneak’ and watch at a friends house.
There’s something which you are now overlooking; a parent has a say in who his child visits. As the child gets older, the values instilled in the child will play a major role in the decisions he or she makes.
