I know what you're asking, brother, but after reading your question for topic, I was prompted by the Holy Spirit to answer from another angle and hope your heart will welcome my post.
We weren't fans but participants in 1985 and got weary from losing because no one was winning. So my wife and I reconciled and now, if she decides she wants blue curtains in the living room and I want green, I ask her to decide and five minutes later I forget all about it and we both win!
Now, thats the Ultimate Fighting Championship!
Hebrews 12:14, Strive for peace with everyone, and for the holiness without which no one will see the Lord.
Holiness is mixed with living in peace. Our right relationship with God leads to our right relationships with fellow believers.
We will not always feel loving toward all other believers, especially after a harsh disagreement, but we must always pursue peace as we become more Christlike. Its what we do, its who we are as children of God.
