I think you can read any heinous quote out loud so long as it isn't your thoughts.
You should try that at work today, let us know how it goes. May I type the words you read? Please attribute them to MakeItRain.
Didn't think it needed said but obviously context matters. You can read out of Mein Kampf in front of Jewish people if you're in a Dictatorship 101 classroom, but not a good idea on a street corner.
There are also different types of jobs/workplace environments. I guarantee you there's a lot of stuff I say at my job/to my coworkers and boss that would get 90% of the workforce fired. However, racist language or slurs shouldn't be tolerated.
Seems like this a gray area, would be a tough call as a boss or administrator to make. Seems like the players aren't very happy with the outcome. He shouldn't have said it, shouldn't be reading aloud what's on a grown mans ipad, that's elementary school behavior. Do I think he should lose his job over it? I'm on the fence.
