“Life begins at conception” but embryos outside a woman’s body have no personhood rights, while embryos within a woman’s body (even those outside her uterus, in the case of ectopic pregnancy) have personhood rights that exceed those of the woman. It’s not about the embryos, it’s about controlling women’s bodies.

And it’s really a viability argument, because if you do nothing, the IVF ones will eventually thaw out and die, and the ones in utero will live. Yet they’re unwilling to follow that argument to its logical extension of a 24-week leeway for abortion.
