If you see a little kid out on the street talking in a high voice (your own son, perhaps?), would you go over to him and begin teasing him about his high voice, and how his balls haven't dropped? I sincerely hope not. Just because this is a game does not make such behaviour acceptable over vox.
EDIT: Removed names to comply with rule #8. I'll just say that the worst player I saw today is ranked among the 'top' five in the game.
