Someone I met years ago explained to me the difference between a personality and an actor, a personality being Eddie Murphy or Roseanne Barr, and an actor being Morgan Freeman and Alfre Woodard or Marlon Brando.
Religious institutions should have religious freedom on this issue. No church or minister should ever have to conduct a marriage that is inconsistent with their religious beliefs. But I think as a civil institution, this issue's time has come and we need to move forward.
If it's true that our species is alone in the universe, then I'd have to say the universe aimed rather low and settled for very little.
