I guess the title really gives it away. I won’t give you any hard and fast rules to live by, namely because each situation is unique. They key ingedient to solving these small disputes (whatever they may be, political, musical, opinion-related, etc) is always grace. Each person has been bought for the highest of prices, has been saved by grace alone, has seen mercy when they deserved wrath, has experienced God’s goodness and is witness to the love of Jesus Christ. All too often we choose to argue over comparitively petty things, and they cause division among us. In 2 Timothy 2:23, Paul says “Don’t have anything to do with foolish and stupid arguments, because you know they produce quarrels.” It goes on to say that the Lord’s servant should not quarrel, be able to teach and not be resentful and to be kind. Sometimes, this is an awfully contrasting image when we look at ourselves. So, take that to heart, and ask yourself: “In the grand scheme of salvation and Almighty God, how big is this issue I want to bring up?”

Basically, don’t be so anxious to demand repentance and make everyone see your side. Rejoice in the fact that you are all saved by the blood, and the petty arguments will fade away like they were never there.
