That's a social phenomenon that has been around since the beginning of civilization. What is new is children's demand for respect from adults. In our Sunday school class, some of the kids will yell out that the teacher is wrong in her statement that they should obey their parents when they are told to wear a jacket outside. But, in a few short years, children with such attitudes who are not kept in check could very easily turn out to be like my young 16 year old friend who believes that I must respect her by allowing her to skip school. She tells me she knows when she needs to be there and when she doesn't.
Children demand freedom.
They believe that they know what is best for them. Respect, in their eyes, is allowing them to do just what they want. The minute they are reprimanded for their unwise behavior, they announce that they are being disrespected. I have seen this from first-hand experience. What I have not yet been able to put my finger on is where kids are learning this.
