Well you wouldn't refer to a doctor as a doctress would you?
In general, having gender distinctions in job titles is unnecessary and slightly offensive.
See i would argue the opposite, actor and actress being a prime example.
you would not call an actor an actress, so why call an actress an actor?
surely this is gender biased from the male perspective? pushing a male name upon a female that i find offensive and i'm not even a woman.
i find it hilarious that were we to do this the other way there would be noise made no end, yet some women accept a male title as making them seem equal when in fact its pushing upon them more gender repression.
makes me think of "metrosexuals" because it nowdays its considered derogatory or even offensive to refer to oneself (as a man) as a gentleman. i feel this is all part and parcel of the struggle we face daily with gender inequalities and we are at risk of loosing our identities as male/female through compromise.
