"So those of us who changed our names haven't seen the light yet"
No, only 50% of you!
because if we lived in a truly equal society where free choice was just that, free, we would see roughly half of women changing their surnames and half of men changing their's upon marriage.
But when something that is apparently a free choice always seems to go in one direction not the other AND there's a dodgy back story (such as the daughter being handed over as property from father to husband) then the feminist antenna goes up.
So, to summarise, it's not to say that you definitely made a non-free choice but that there is a 1 in 2 chance that you did.
And it's certainly not patronising (or intended to be) to say that, because we ALL make non-free choices ALL the time. Hell, today I shaved my legs and put on eye makeup and lipstick. In MessyUtopia there would be no need for such frivolities but I live in this world and I've been brought up to see this behaviour as normal. And, it makes life easier.
Hate the game, not the players.
