In fact, their Bible explicitly condones abortion. Priests would administer abortions in the form of "bitter water" to women who were accused of adultery.
Their god doesn't give a shit about babies, but apparently cares a lot more about keeping women in line. Almost like the whole thing was written by a bunch of men in power who wanted to keep their power. Hmm...
My wife kept her name (both of our names are important to us, and neither of us care about tradition). So far no real issues, just people who know one of us assuming the other shares a last name. Unless it's someone we're going to interact with a lot or we're filling out paperwork, we don't bother correcting them.
We are trying to have a kid, and if we succeed we'll give them her last name. So... I'm super looking forward to being a man picking up a kid with a different last name and all the assumptions I'm probably going to have to face. I'm just hoping by the time that happens this will be a normal enough occurrence that it won't be a big deal.
