I just found out that people think it's sexist to make mille pregnant

So apparently people think it was bad writing and sexist to make millie pregnant. They were saying it was so stereotypical for Mille to be mad about not completing the mission. "Chalking it all up to women mad" they also said this is one of the things to made it a terrible final to a terrible season....just why are people so Hateful? It's so irritating...
