Advise a friend who responds to conflict by confrontation and why the strategy is not healthy for sustaining positive relationships

Responding to conflict with confrontation will just lead to more and more arguments with peers, family members and loved ones. People will start to avoid the friend because many people do not like confrontation and prefer to deal with conflict in a calmer more understanding way. The friend needs to take that approach in order to sustain positive relationships. The calmer the approach to conflict the better. A mutually supported understanding needs to be reached in conflicts in order to resolve them peacefully. Aggression and confrontation just leads to more anger and upset.
