Wouldn't you like to live in a world without drug addicts, murder, rape, and where the worst thing that can happen is your mom saying no when you ask to go to a friends house? Because that's the world I lived in until I was 10 or so. Frankly, if my parents had let me have free rein over the movies I watched, games I played, and sites I visited, my childhood wouldn't have been near as innocent and happy as it was. I'm not saying kids should be left in the dark forever, but why deprive them of a chance to live in a near perfect world (in their mind). What purpose does it serve?
