Well....
When some kook blows up an abortion clinic or murders an abortion provider, it's very common to hear even strongly anti-abortion Christians condemn the act. It's very rare to hear any Christian speak approvingly of murder.
When the "Christian" Druze entered a refugee camp in Lebanon back in 1982 (or was it 83?) and murdered a lot of innocent people, there was worldwide condemnation of the act.
One area that was weak was when many Catholics refused to condemn the Irish Republican Army for committing terrorist acts and murders.
