Yes, mc, current social mores say that holding women responsible for actions is unacceptable (even though a more even handed evaluation would likely prevent some misadventures similar to the situation of  choosing to walk down a safe street to avoid robbery).  This is fine.  This is a choice of society which is justified in various ways.  The point is that we pick and choose when we hold people responsible for their actions.  In the school case, it absolutely is discrimination to differentiate between two equally qualified students solely on the basis of race.  We chose to commit this discrimination because we believe that the greater good is served.  So discrimination can be good as well as bad.  Who knows what is right?  Its a beautiful day out today.  The world turns regardless of the pressing issues of mere humans.
