It’d be interesting if men took on their wife’s first name, so it would immediately indicate to others if a man was married or not. And then there’d be pushback, in the same way there is to the ‘Mrs’ and ‘Miss’ titles, and parents would start naming their sons with female names to start with. (it works less well the other way around, because there’s already girls called ‘Dylan’ and ‘Taylor’, etc).
In this world I suppose we’d start referring to people by last names more often
Americans already have a confusing number of unisex names, so why not make all names unisex. The gender noun confusion clearly isn’t enough, so why not max out the potential confusion you can create.
I second your proposal. Just call them all „Bart“ and „ Maggie“ if female
Why stop there. Just keep on using all the usual names, but make them all unisex.
For example, if Tony is texting to Anna, He will have no idea if Anna is a he or she until they meet face to face. Also, Anna might be expecting to meet a woman, but will be surprised to find that Tony is actually a guy. Then, Anna tells Tony, that they should really talk to Karen for some weight lifting tips because he’s been lifting for years.
Sounds confusing, but you’ll actually know who is married and who is still single. Pretty handy, eh?
Here’s one example of this system in use https://en.wikipedia.org/wiki/Icelandic_name
Edit - I realize I probably misunderstood the question. But as said in another comment, it’s just a swap if we’re not talking about patronymic/matronymic naming systems.
Used to be wives were referred to as “Mrs. (Husband’s Name)”.
Though I’d think anyone calling my wife “Mrs. jordanlund” would be swiftly killed and nobody would find the body.
About a year after I got married, my buddy Spider was over for dinner.
We were in the kitchen doing prep as a group, because it’s fun. Spider, being a fuckwit, decides to start calling my wife Mrs Sasquatch (sasquatch being one of my nicknames).
She glared at him the first time and said “I have even less body hair than you, Mr I wish I was cool”
Which got plenty of laughter all around.
By the fifth or sixth time, Spider had run the joke into the ground as usual. He asks if Mrs Squatch could hand him the eggs. So she did. Right to the face.
Which got plenty of laughter all around tbh. Spider may be a twat, but he takes as well as he dishes out.
