I can understand women (or men) not wanting to change their last names. Although in most cases THAT IS YOUR FATHER'S NAME, not your mother's, so it is already a bit strange. But fine. Keep your maiden, take your husband's, pick a totally different one. Whatever.
What I can't understand and don't like is all this ridiculous hyphenation stuff. It makes everything very long and complex. I suppose it was meant to be some type of strange compromise, but it is more of a kludge. I don't care what your last name is, I just wish everyone WOULD JUST PICK ONE NAME. At marriage, my mother changed her middle name to be her maiden name.
And if you have a hyphenated name, what are you going to name your children? This hyphenation stuff? And if so, what are THEIR children going to be named? 4 hyphenated last names? And their children, 8? Then 16? A better plan would be, everyone keeps their single/original last name, male children take the father's name and female children take the mother's. Done.
In any case changing your last name to your husband's with marriage is not a sign of "subservience", it is a just a practical way to keep a single name for a family unit. And usually done in love and dedication. Good grief.
