I agree that abortion is about the fundamental right to bodily autonomy, wrote the same point before, and think too many people miss that & liberal philosophy in general. Everything in their first comment is great.

However, I think they mischaracterize the objection.

When you say “rape is the exception” what you say is this: You are treating pregnancy as a punishment.

That's not necessarily the argument. A more challenging argument: someone who willingly places a body in themselves creates a duty absent from someone who has not. The host willingly placed inside themselves a body that did not choose to be there & now depends on the host. Therefore, the host has an obligation to fulfill their duty to that body.

An analogy might be a life-saving procedure dependent on a host that almost certainly results in death when interrupted. Someone volunteers to a random lottery for a host & is selected. They allow the procedure to begin. However, midway through they demand to interrupt the procedure.

While I'm in favor of abortion for various reasons[^golden], I think this is a more difficult argument to counter. Maybe a better arguer knows a good counterargument.

[^golden]: primarily, if I were a fetus, I don't think I'd mind getting aborted
