This is a condition named after the Motion Picture Association of America (MPAA) which causes people to veiw sex-related things as inappropriate, yet be perfectly fine with violence. Sufferers also find homosexualaly much worse than being straight.
When asked to explain why somthing is inappropriate, the will often say "those ideas do not need to be put into children's heads" but will not actually beable to explain why somthing is bad.
