The pro-abortion argument has always started from their end goal (unlimited casual sex with no risk of responsibility) and worked backwards from there. They find their own “logic” and “principles” top-down based on whatever will conclude the way they want, regardless of whether those actually make sense. It’s just to play along with those of us with real principles. And theirs don’t make sense, which is why they hate actually thinking about it, and why they always draw things back up to what it’s really all about for them. “But thinking this way will prevent me from having all the sex I want!!!”
