Yes this is true. There have always been adults who behave badly. However, that doesn't have anything to do with the changing length of childhood. In cultures where a person was considered an adult at 15, there were older people behaving badly. And in cultures where a person is considered an adult at 18, there are older adults behaving badly. This is not about adults killing or stealing or just acting like asses. This is a very specific issue. 18 year olds demanding that colleges treat them like children in order to protect them from being offended.
