lol Cofty, we're at cross purposes
I did not say that I refuse to use Ms. I said - "I have never referred to anybody as Ms in my life, I have also never referred to a man as Mx and never will."
I have never been asked to refer to somebody as Ms. I'm amused that you would presume to declare my opinions on anything "unacceptable".
I thought you found Ms unacceptable, I didn't find your opinion unacceptable. I suppose I have to contact people I haven't met, in writing, hence my fairly frequent use of Ms. Was the "never will" about Ms or just Mx?
