Someplace Someplace in my archives, I have a poster with a quotation from Adolph Hitler in which he bemoans the plight of decent society where children have lost their respect for authority. I think the ancient Greeks used to complain about it too. I'll try to find the Hitler poster. It must be nice to be able to give such an assured answer on such a broad 'problem'. I agree with the previous two posts in that it is a part of childhood.
Some children are less rebellious than others.
Is it because they have never heard of Roe Vs. Perhaps you should open your mind a little bit and allow other possibilities. I happen to think that Roe Vs. Wade was a great leap in the direction of feminine equality. To peg it and it alone as the reason for rebellious teens isn't exactly rational thinking.
