As I said in my earlier post, @Nordicrain, I am of a generation where it was the norm to change your name and take the title Mrs when you married, and I have been married over 30 years now, so this is part of who I am. I was also very keen to leave my maiden name behind, as it had been used to bully me throughout secondary school, so it has very painful associations for me.
Dh wears a wedding ring, because he is happy to advertise his marital status to people he meets, and if there was a change of title for men that mirrored the Miss to Mrs change, I think he would have chosen it.
But I’m not up in arms that he doesn’t have that choice, partly because he isn’t bothered, and partly because I can sympathise with the OP’s views, and if we want to move towards a single title (if a title is needed) for women, then surely it would be counterproductive to add in extra titles for men.
I honestly believe that the balance is shifting, and in time, the Miss/Mrs titles will fall entirely out of favour, and no-one will bat an eyelid at a single title for women that does not advertise their marital status. But I think it is better for the change to be organic, not forced.
I do think a good start would be taking all titles off forms - that would not bother me at all.
