Were we to adopt the French/German model with Madame/Frau and address every woman as 'Mrs' once they reach adult years, I'd not have a problem with this.
The UK differs in that women have 'maiden' names, together with titles which as good as announce their sexual status on superficial acquaintance. The deed poll site on the link posted above makes repeated reference to maiden names. This isn't only antiquated and sexist but utterly nauseating. Women have surnames, or family names. We're not adjuncts to men, and the idea that our sexual status connotes the entirety of our actual social status - well, to coin a Mumsnet gem, it boils my piss.
I insist on 'Dr', a thing I once thought pretentious and said I'd never do, for precisely the above reasons. It's neutral, defines me in a professional sense and not in relation to any man, and it avoids any silly, snippy, snarky discussion (yes, I've had them before I qualified) about the Miss/Mrs/Ms nonsense.
Easy get-out for me, but the point is that women shouldn't need a PhD to achieve a moderately respectful title. In fact, titles overall are hogwash. Why are they necessary? A name is sufficient to identify anyone surely.
As computer fields, shopping sites, web pages, login screens ALL still require this anachronism, I'll use Dr if available or if not will accept Ms. Miss or Mrs? Just no.
