Life is going to present you with lots of unreasonable people, events and conflict (unless you have lived in a sheltered hugbox), you can’t control others, nor is it morally right to do so, but you can control yourself, your emotions and how you react to things, this is your true and only morally just sphere of influence.
A society that encourages thicker skin is more emotionally regulated and more prone to conflict de-escalation, do you think any Police or security training worth its salt produces people that will answer insult with offence? “Are you disrespecting me?”.
You cannot control a situation if you can’t even control yourself.
