My objection is more to her doing it because she feels this is something that women should do. Your choice to change your name is absolutely your choice, and there are a number of good reasons to do that - I just don't think that being part of a 'great tradition' is one. I'm very keen on the right of any individual to choose how they are called (while I disapprove of Ashlee Simpson's reasons for doing this I would defend her right to do so), but there's a difference between making that choice because you feel that in your individual circumstances this is the best thing for you, and doing so because there's a normative practice that decrees how you should define yourself on gendered terms.

Um. Hope that makes sense?
