And there’s a coherent position of “the line needs to be somewhere and birth is the Schnelling point, so I’m contingently pro-abortion but anti-infanticide, pro tem”. But I don’t think many pro-abortion folk would endorse that position.
There’s at least one. Actually, I thought this was the obvious answer even before I knew what a Schelling point was: there’s no clear point at which humans become sapient and it probably isn’t a binary issue, but the line needs to be drawn somewhere, putting it at conception implies a lot of nasty tradeoffs, and so we might as well put it at the other big obvious developmental transition.
(There are smaller and less obvious alternatives, of course. One’s the viability standard that’s usual in the US post-Roe. Another is the point of “quickening”, when fetal movements become obvious to the mother, which has seen historical use in this context. And then there are various developmental stages post-birth, as are used in many older cultures to mark when to name the kid. I think these are all substantially worse Schelling points as things stand, but you could make an ethical case for any of them given certain assumptions or additional data.)
