I don’t want to be called Ms, it’s an annoying made-up word
Oh man, I've got some terrible news for you about literally all words.
that sounds stupid and confuses people about how to pronounce it and it doesn’t have history behind it like Miss/Mrs.
It derives from the same root word as Miss and Mrs so shares a history - and Mrs and Miss landed on their current usage later than many people think (they used to be used quite differently), and has a history going back to the 17th and 18th centuries. We're reviving and reclaiming it.
I'm not sure about the pronunciation issue - do you have trouble saying 'fizz' or the second syllable of 'Mrs', depending on whether you favour the 'i' or 'schwa' pronunciation?
It's interesting that male titles have pretty much totally done away with titles that signify social status and power dynamics, but we cling to the female titles that do likewise. We don't use Mrs/Miss/Ms in the same way as we use Mr when talking about the chair of a meeting, how Kamala Harris is referred to - none of those carry the same gravitas or impact as 'Mr' when being able to say 'Mr Chairman' or 'Mr Vice-President'. Possibly because 'Mrs' is so tied up in 'wife of' meaning - so 'Mrs Vice-President' could 'read' the wrong way.
