Rita Mae Brown:

Once you start lumping people into groups, you rob them of their individuality.  It's easier to kill them if they're blacks or gays or Germans or Muslims.  But if instead of groups you are looking at individuals from those groups, William Raspberry or Ellen DeGeneres or Steffi Graf or Salman Rushdie, then those categories fade away.  You're faced with a complicated human being, like you in some ways and not like you in others.  The fun is finding one another out.
