...or, stillstanding, no need to make a point which I and others have made over and over, when I can make a lighthearted and quite funny comment on what I find a truly remarkable position, viz. only knowing one 'Ms'. Whether or not that's true, I'm not sure why anyone's experience is relevant. Ms is clearly not as popular as many of us think it should be, so it's hardly a numbers game.
But since you seem to be keen, I'll make the one, inarguable point again:
Men change neither their names nor their titles on marriage. Women traditionally do. This is inequality.
Inequality - not equal, one being treated differently from another for no reason other than gender - geddit?
To be treated equally the broad choices are:
Men and women remain Mr or Ms Theirownnames forever (yes yes, that means her father's name in the first generation but let's not split hairs here). Many of us do this already but the question of what to name children is a potential problem here.
Men and women have a change of title and name on marriage (so we have to bring back Master for those proud bachelors, as well as give them a new or double-barrelled surname)
Ms and Mr become Ms and Mr Jointname - which may be new, or double-barrelled (and if the latter, the female and male lines can use the appropriate part of the double barrel on marriage, so both easily traceable for genealogists.
It will happen one day. Meanwhile there's nothing wrong with being in the avant-garde.
