And you'd be arguing from a position of no understanding, and in extremely bad faith, much like the rest of the arguments in this thread and on this forum. Do you do difficult endgame content? Judging by your statement, I do not believe that you do.
The vast majority of people I have raided with that use parsers, never talk about them in game, and never harass anyone because they're not stupid and they know it's bad behavior that will get them banned, as it should. I've been playing this game since 2017 and I've never seen anyone get harassed over DPS in matched content, ever. Granted that my experience is not reflective of the entire community, but neither is yours, and neither is your analogy.
Also worth saying that nobody is trying to argue that harassing people over metrics is okay, so not sure why you're even using it as an argument to be honest.
