Sometimes, we need to be peacemakers rather than just peacekeepers that means taking action instead of keeping silent.
The only thing to do is walk away, that is the only there will ever be peace, I don't know what else to do, and I surely don't want to fight with you, all I want to do is get to be friends, and put the past behind us, that is the important thing, I don't care about anything else.
Sometimes that's exactly what evil wants. For you to walk away and not argue. Sometimes that's the worst thing you can do. Know the truth.
But sometimes it's healty to debate, to communicate your thoughts and feelings. From time to time to argue as well. Don't run away from all the conflicts, choose some to handle and some not to handle. If you feel your soul, that is because you have one. Choose wisely whom to argue with.
Arguing is actually healthy given that it is targeted towards improving behaviour. Blind character attacks and unhealthy insults take away from the meat of healthy arguments.
