My greatest prayer is that those who are authentically born-again would see every disagreement as an opportunity to go back to prayer and the scriptures to make sure of what they know or to correct a wrong belief.
Disagreements are not acts of hatred, they stretch and help us to become stronger and more resolute to seek Christ instead of defend what we like to believe.
Seek Christ, Seek the Word of God and pray for wisdom>
James 1:4-6 "…4 Allow perseverance to finish its work, so that you may be mature and complete, not lacking anything. 5 Now if any of you lacks wisdom, he should ask God, who gives generously to all without finding fault, and it will be given to him. 6 But he must ask in faith, without doubting, because he who doubts is like a wave of the sea, blown and tossed by the wind.…"
