It's talking about female to male trans people. They can get pregnant, but don't get represented because Caitlyn Jenner is an idiot.  This whole thing is still idiotic. It's just going to be a whiny circlejerk about how hard it is to be fat, how everyone makes fun of them, how their oppressive doctors tell them it's not medically safe to be obese and attempt pregnancy, how it's their right to be classified as healthy even if they aren't, and then it will be published as scientific research by an organisation that claims to be scientific yet doesn't understand, as you say, that obese is a medical term and not an opinion, and that comes with many definitively proven medical risks. I can't even with this level of stupid.
