Our government is now pressuring the UN to stop using the term 'pregnant women' link. Because, you know, men can get pregnant too 
Why does this matter? What do you think will happen to our hard-won and still inadequate maternity rights if women are no longer protected because only they can get pregnant? Almost all those rights are based on avoiding sex discrimination: only women can get pregnant, so - if your workplace makes life particularly difficult when you're pregnant, it is discriminating against women. If men can get pregnant too, that difference is eliminated. This argument has already been made in a case in the US about the right to breast-feed.
Oh, and it's an Orwellian lie designed to erase women.
