>And it's somewhat unclear to me why this should be a federal issue at all... isn't murder a state issue?
That's an odd framing for a self-described "pro-abortionist" to use, but no, obviously federal law against murder exists[0].
But of course the question of whether or not abortion is a matter of murder, fundamental bodily autonomy or both is a quagmire not worth getting into. Not that it's relevant to Roe v. Wade, or its appeal, because that rested on the question of the existence of a fundamental right to privacy and stare decisis.
I mean, read the dissenting opinions on Dobbs[1]. I think a good case is made there as to why this shouldn't be an issue left to the states, and why Roe wasn't repealed because it was bad law, but because the court was stacked with ideologues who were opposed to Roe for religious reasons.
You should be at least as angry about that as Roe itself, if not more so because that represents a far more egregious corruption of the system, but I suspect you aren't.
