Consider two identical embryos: one gestating, one in a lab dish. Pro-choice reasoning grants rights to neither, yet the only difference is location, not nature. That's the structural gap in my opponent's case: it defines personhood by geography. If rights depend on where someone happens to be, that isn't a principle, it's a boundary drawn for convenience. The other side must explain why the womb specifically switches moral status off, and so far no one has. Until that gap closes, the pro-life position rests on firmer ground.
