It's your responsibility as a parent to restrict what your child is exposed to. Yes I am a parent my "little" girl is 21. My wife and I controlled (not sure its the right word really) what games, movies and TV she watch up until she was an age responsible enough to make informed choices in our view 16. If you as a parent let your child play games, watch movies and TV that is not age appropriate. Don't complain when said child acts up.
