>Well, you simply have different assumptions than some (most?) of us. For me, "man" and "woman" mean biological sex, not gender
Um no, my view isn't an assumption. Gender isn't sex. People don't call a boy a man or a girl a woman. Maybe US western culture assumes sex = gender but the rest of the world has some form of distinction from sex (biological) and gender (social).
>Also, for me, a "name" is about the least personal thing about myself - it's what others call me, so it's inherently a cultural thing that depends on the social contract. For example, if you change your name without a good reason, most people would simply assume you're trying to run away from your past or avoid justice.
In our US western culture a name is a name whether given or self-attributed. No one demands Prince or Madonna to give their legal names. We know them by those names in terms of their public actions. If I greet myself as Veronica it's safe to assume that is my name. It doesn't require a background check in a social setting like a party or a meetup. It's not like I'm looking to get a security clearance.
Also, there's no such thing as a good reason to change one's name. You just change it for your reasons. The good and bad about it is merely a subjective valuation of the act of the change. It has no bearing in terms of the character of the person. If you can't just accept my name is Veronica upon first meeting then maybe you're just a jerk?
