It stops being "amateur comedy" when it starts directly interfering with other people against their will.

If I go to a comedy show, I accept that I might get offended; that's on me. The power dynamic when I go to work, where I am expected to work with my team in order to get compensated, is massively different.

Nobody is making claims about "policing" (whatever that means in context). I don't care about words impact on "society as a whole" as some abstract concept. Society as a whole is comprised of people, and starts with the people around you upon whom you have the most direct impact. If you knew you worked with (or played a game of CoD with) a gay person, or a black person, how would you feel about using those words? That's why it's "bad for society as a whole"--because it's bad for the people right next to you.
