I assume someone said that the employee's behavior -- directed at anyone -- should be considered inappropriate?
For example, let's say I worked at a grocery store, and I called a black customer a "Fucking homeless loser." Now, that may be racist, but most importantly, it is incredibly crude and mean spirited. I shouldn't be fired for racism, I should be fired for being rude and inappropriate to customers.
Similarly, this man is an online journalist, by trade. He is held to a special standard that random-guy-on-GAF would not be. If he's crude and mean spirited to another member of the gaming community in public on the internet, he deserves to be fired for that, whether she happens to be a man or a woman.
