Probably older, probably more experienced, subject of a news story, in a fairly professional context? Kind of offensive (IMO).

I think outside of common terms like "chick flick", this is just like using "girls" to refer to adult women - think to yourself, if you replaced the term with something like "boy" or "dude" how would you sound?

I don't really go on crusades about these particular uses of words because I feel there are better fights to fight, but I would never refer to a man in this particular context as a dude. Maybe I'm overly politically correct, but I try to be respectful to everyone.
