It may be how it is but it is not how it should be, where do the scriptures say to act one way in church but another outside of it? it doesn't the scriptures say what they say there is no loop hole around it to act a certain way here then another there either you obey the word of God or you don't you don't get to pick and choose.
The verse you posted has nothing to do with acting like children bickering with each other it speaks of how truth is wielded but where does it say to bocker amongst ourselves?
Galatians 5:15:
"But if you bite and devour one another, take heed that you be not consumed one of another
1 Thessalonians 5:11 states, "Therefore encourage one another and build each other up, just as in fact you are doing
John 13:34-35, Jesus gives a new commandment: "A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all men will know that you are my disciples, if you have love for one another."
2 Timothy 2:23-26, which advises against foolish and divisive arguments and encourages gentleness in teaching, and
Philippians 2:14, which urges believers to do everything without grumbling or arguing. Additionally,
Proverbs 20:3 suggests that avoiding fights is a mark of honor, while
Proverbs 15:1 highlights the power of a soft answer to diffuse anger.
So it may be your opinion that I am over reacting but the scriptures say otherwise
