BlingLoving -- I agree with your points.
Yes, you can be Ms [DHSurname], to whoever asked it earlier.
MissWooWoo -- they are taking the piss out of the married woman's traditional title for political reasons.
Maryz, why should women announce in shorthand that they are married when there is no corresponding shorthand announcement for men?
If we are going to claim that taking away the choice of Miss, Mrs or Ms is removing some sort of right from women, then we should restore Master for boys and invent some title that conveys to the world that a man is married. Then men could also choose. They have been robbed of Master and denied the option to proclaim their married status to the world. Giving them a choice of three titles would only be fair, and equal.
I think there should be a box with the choice 'I'm With Stupid'.
