As far as I’m concerned, it doesn’t matter why any woman wants to end her pregnancy. If it’s to select for sex, that’s her choice.
We don’t, in theory at least, have abortion on demand in the UK. It’s of course just fine to argue that we ought to have, although I and some others will disagree with you.
But given that we don’t have the law stating that we do, don’t you think that we should all be obeying the law?
