Your thread title and your reaction makes me think otherwise. I'm not in-line with a straight-up total ban on abortion after 20 weeks, but the pro-choice reaction in this article is full of straw man and slippery slope arguments.
This is no different from any other anti-abortion bill, except pro-choice supporters are using an extreme argument that is actually completely nonsensical. The only reason a fetus *might* (since the exact time of conception is pretty much impossible to know) be 2 weeks older than it actually is is purely for medical consideration, and not so people can do some kind of conspiratory preemptive measure to eliminate birth control everywhere, which is the precise reaction this article is trying to elicit.
This is a really crappy article with the way it is written and it gets on my nerves. I dunno, big pet peeve of mine.
