Stereotyping is probably the biggest cause of our current public unease. It is not a new problem; it is a thinking skill or lack thereof that challenges us all. When we fail to appreciate the individuality and uniqueness of others, then it becomes easier to make blanket assessments. (Some examples come to mind:  Immigrants might be rapists; POWs are losers; journalists are liars; black people have unhealthy eating habits.)  We all have sloppy thinking.  We should try to do less of it, not more. The foundational flaw in your response is the fact that you were stereotyping an entire group and then pointing the finger at all sorts of other things to defend your sloppy conclusions.
