That was the topic on the Ask An Atheist podcast this past weekend:
A few months ago we put our an open call to our listeners to provide us with non-religious reasons to oppose abortion rights. While some listeners responded with a few arguments they’d encountered, we heard very few atheist abortion opponents.
The majority of arguments against abortion are religiously motivated and not based on science. Science says nothing about souls, about any god giving the breath of life or dreaming us into the wombs of our mothers. Because of these deeply held beliefs, religious folks then attempt to make all sorts of reasons why abortion is bad, including but not limited to misinformation that abortion is dangerous, or that it leads to murder or infanticide being legalized, or any number of spurious arguments.

I listened to most of the episode in the car yesterday and I thought the hosts did a really nice job of taking the objections people had for why abortion was wrong — and calmly, rationally discussing why those objections made little sense. I would’ve loved to see a pro-life atheist included in the discussion just to make things interesting, but I’m sure if there are objections they didn’t address, they’ll answer them on their site over the course of the next week.
