Look, adrienne, in the nicest possible way, it's clear from your posts - insofar as it's possible to read them, as they are quite garbled -- that you are a fearful, conformist reactionary who thinks the status quo is somehow sacred, rather than the inglorious remains of patriarchal socialisation.
You're terrified of what people think of you, you're afraid that, were you to use your own name after marriage and give it to your children, you would be assumed to be an Unmarried Mother, or your children to be from a Broken Home, and you have a lot of under-researched, under-thought ideas about the importance of marriage and male pride, and giving in to men. You also seem terribly afraid of men.
Life isn’t always fair, and the more we only think about ourselves, the more the future generations will suffer. It’s not always about you or how you feel. We sometimes have to do things we don’t like doing.
Absolutely, life isn't always fair and we end up doing things we don't like, but that's entirely irrelevant to this thread, which is about giving your children their father's name even if said name is Shitsandwich -- that great thing about naming your children is that, bar some rules about avoiding obscenities etc, you can name your children absolutely whatever you like. The OP's descendants will assuredly not suffer if her name or a double-barrelled name is passed down.
but you’re also teaching your child by way of example that they too should hold a special place in our society and regardless of the structures those people value, that they don’t need to follow them if their feelings might suffer as a consequence
Again, you are vastly inflating the importance to our society of passing on the father's name. Who values passing on the father's name? I certainly don't. Large number of posters on the thread don't. Large numbers of other cultures don't. Spanish society has not fallen apart because people tend to use their mother's first surname and their father's first surname.
And absolutely, I will be teaching my child that there is absolutely no need to adhere to outdated 'traditions'.
