I'm back. I think you should tell your parents of your anger and frustration and the reasons why (i.e. injustice, manipulation, no logic or reasoning, etc.). Fight the good fight. Open your brother's eyes and help your parents have a dose of reality in their make-believe world. Make sure your brother knows that he has you and others to rely upon when he changes his mind. I think it will help him to know that there is support. Intense conversation can still be a loving experience as long as the decibles don't get too high. Your parents should realize how loopy they are. They think they are model citizens.
