What, exactly, indicates that they haven't played it? All I see is indication that they may not have read the books. Then again, neither did I, so I can't make a fuss about that.

Also, I have no problems with someone calling a male elf "young man". Not sure what else to call a young male elf - "young male elf" sounds silly and too long if you're directly addressing someone, and "young melf" sounds even worse. "Young male" perhaps, as a generalization across races?
