Pope was leader of a sect that has spawned some of the ugliest religious violence and sexual abuse in history.   He also abused his religious standing to interfere in internal politics in the USSR (compare US views about non-Christian religous leaders who pontificate (choice of word intended) on internal US civil matters). His teachings on birth control condemned thousands to lingering deaths and/or miserable lives.

Ought we universally to revere him simply because he is dead? Compare the hypothetical requests for silence for Hitler, or Hussein, or Pol Pot (etc, etc)? Certainly some deserve to be vilified as well after as before death.
