I don't think anyone here is saying that the problem are the "bad words" themselves.

I'd wager that a lot of people here are probably fine with someone shouting "motherfucker" at a problem in your screen, or saying that something is "fucking stupid", but draw the line at shouting or telling this to a person... especially in a public email, and even more especially when you're in a position of power over them.
