--a nice Ayn Rand defense of abortion might be something to toss into their kennels. (Not a hobby of mine, so I don't know whether it has been tried or not.) Lots of quotes at the following URL.

I cannot project the degree of hatred required to make those women run around in crusades against abortion. Hatred is what they certainly project, not love for the embryos, which is a piece of nonsense no one could experience, but hatred, a virulent hatred for an unnamed object...Their hatred is directed against human beings as such, against the mind, against reason, against ambition, against success, against love, against any value that brings happiness to human life. In compliance with the dishonesty that dominates today's intellectual field, they call themselves 'pro-life.'--Ayn Rand
