I dunno. I see Klingons as extremely old-school, culturally. They treasure old ways of fighting (bat’leth, qutlutch), worship (Kahless, dark, candle-lit spaces), being (honor bordering on chivalry, belonging to the house of one’s father), and singing (manly voices–Michael Dorn even lowered his speaking voice for TNG). For me, hearing Klingon high-pitched voices during a crisis was analogous to hearing “Eek! A mouse!” It was funny, but I’m still experiencing cognitive dissonance.
