This is the recurring argument of people who insult others and rage in chat: "You're too soft getting offended by words, grow some balls."
Truth is, you're not getting reported because you offend people. Nobody cares about insults from immature douchebags hiding behind their computer screens. You are getting reported because it creates needless negativity.
Imagine playing football, and having in your team a guy that constantly insulting his teammates. Even though you don't care about the insults, would you keep him in your team indefinitely ?
