Sadly because everyone THINKS THEIR RIGHT and they won’t be mavater they won’t give in and admit they’re actually wrong or even if they really are right but just for the sake of peace let the other person who your in a fight with get the pleasure of feeling like he won and get the fight or argument over with and move on with your life and in that merit Hashem will send Mashiach and rebuild the 3rd Bais hamikdosh.
There is a benefit in milchamto shel Torah. It helped the Beis Hillel through allowing the Beis Shamai to come first because of their humility. They arrived to the truth by seeing the other side and not being blinded by tunnel vision, seeing only one side of an argument. Being humble, we will admit when we are wrong creating peace,
