Like www, I can be a bore on this subject, probably much more actually. And what follows might sound a bit bra-burning-ish & over-excited, but try to imagine it said with a light debating tone, because that's the tone in my head.
First of all, what's wrong with Ms? Why does it sound stupid? Because it's a recently invented word? But so is 'blog, and that's newer AND sounds far stupider, but no one questions that word. And why should "Ms" offend? All it means is "I don't know you if you are married or not." What's more offensive, I would think, is jumping to the wrong conclusion about someone's marital status by using "miss" or "mrs" erroneously. And I, personally, find it demeaning to be identified by my marital status, as though it's somehow a relevant detail about me or who I am. If I had a dp & not a dh my life would be exactly the same but I would be referred to no, identified bya different title. Isn't that weird & doesn't that warrant questioning and changing?
Secondly I'm also a bit bored with the retort that if you don't take your husband's name, then you take your father's name. IT'S TOTALLY DIFFERENT. How can the two be compared? Regardless of the origin of the name you were born into, it is your name. How can it be so easily relinquished to a husband who 50% of the time be around for the long haul? (US divorce statistic)
My kids have my husband's name and I have a big problem with it, to be sure. I know it flies in the face of my beliefs, but I just don't know what the alternative is. Double-barrelling would be disasterous for us, and their taking my surname (as Trifle suggests) is equally unfair to dh. And "making up a new name" as someone suggested would seem not to be respectful to history somehow IMO.
But I guess this is about where you find your identity. For some, nothing is in a name; for others, everything is in a name. And some people, like me, are more pathologically "individual" than others--that is, we view ourselves as a whole, not half of a whole. Others, I guess, do view their partnership as their main identity.
Are you sorry you started this Trifle?
