I would hope that love-based marriages are what we all aspire to. At least in my belief it is. I’m not telling people what they can’t do with their lives. There are plenty of things I disapprove of, but I don’t go around berating people for not living as I would like them to.
The OP sounded like they didn’t like this kind of arrangement for children, possibly for the same reason that I don’t like it. So I was letting them know that I agree and sympathize but at the end of the day their child is an adult and can do whatever they want. It is the parents’ decision with how they will react to things they don’t like their daughter doing.
I have a coworker whose maiden name is Dykes. She was very happy to change.
