Agree. Murdering someone because they are murdering others makes the perp no better than the scumbag he/she killed. The perp acted as a zealot.
If you TRULY believe that Abortion is murder, then you cannot condemn anyone who would do anything to stop this mass murderer from continuing in his crimes.
This is where the rubber meets the road.
If you call abortion murder, then this was justifiable homicide.
If abortion is not murder, then Tiller was the victim of a heinous crime and his killer should be condemned.
