If we never expose our kids to this type of stuff (R rated movies, mature games, etc), when they actually do see mature content, or hear a bad word, they won't know what to think. Why? Because no one ever showed it to them, so they won't know that it is wrong. My dad took me to a Stone Temple Pilots concert when I was in the third grade. He would point out the smell of pot and explain to me what it is, and why I shouldn't use it. There will people saying "F*ck this!", ect. Instead of him covering my ears, my dad explained to me what the word was and that it was bad. I think if we stop sheltering our kids so much and actually expose them to certain content, that we will hear less about kids doing drugs or people having ramapages at their schools, etc.
