My boys saw a "woman" get a shot to the head. Why would you call her a prostitute? There was nothing indicate that she was. My sons' also saw other people being hung, stabbed, impaled, blown up and otherwise killed for standing up for their belief of freedom.
On the school bus, they see their peers engaging in oral satsifaction. At school, they see pictures of naked girls giving oral satisfaction to males. They learn how to take pictures of their peers with their cell phone cameras by pointing them under the walls of stalls in the bathrooms. This is what the school terms as "safe sex."
On the television, they hear our President proclaim Iraq's independence and see pictures of their cousins being killed...in the name of oil.
Personally, I don't have a problem with the violence in the fantasy of POTC. I have a problem with reality.
