The context of Jesus' talk was that if someone resisted a roman order they would face crucifixion. The best response to a roman order was to be as accommodating as possible

Liberal - love your enemies and pray for those who persecute you
Loving our enemies is not always possible. The real message is that we should take responsibility in areas of conflict and stop the never ending cycle of hatred
They accept the teaching of Jesus as authoritative so despite provocation, they will not resist attack and will try to show love towards those who might be their enemy (just like Jesus did)
