I thought the abortion analogy in DW was most definitely there and most definitely intentional, from Clara's exclamations about "killing babies" (which reeeeally rubbed me the wrong way) to the Doctor's comments about the decision belonging to "womankind" and how it wasn't his moon, so it wasn't his place to decide.

I was scoffing from the very beginning of this episode, really. "It's one innocent life vs. all of humankind" is a really shitty decision to have to make, but the choice seems pretty clear to me. That's not to say that I disliked the episode overall, even with Clara giving a big "fuck you" to the entire population of Earth. It had some good things going for it, like Clara's argument with the Doctor at the end or, um...probably some other stuff I'm forgetting...but the anti-abortion subtext was headache-inducing.
