One Idea That Must Die

In this thread, tell us YOUR one idea that must die--an idea in culture, politics, religion, science, etc. that you think has outlived its usefulness and/or actually causes harm. Make sure to tell us why (you think it has outlived its usefulness and/or actually causes harm). We all understand that we are not scientists or economists or whatever--we are speaking freely as 30-some L.A. residents who are connected to this English 103 class. So, you don't need to worry about your qualifications for deciding which idea must die.

You may pick an idea that is specific to one community (e.g. "In my religion we believe that ---- but I think this idea is harmful because---" or "In my country there is a law that ____ but I think this idea is harmful because---") or you may pick a more general idea. In short, be creative and pick anything!
