This is the actual Republican platform. The guy you're arguing with doesn't actually believe that protofetuses are worth trying to keep them alive. He just wants to be able to tell you what to do, and guess what? If he can force you to die over a nonviable protofetus, that means he has power over you, which is the entire point. He doesn't care about you, save that he doesn't want you to be able to keep him from killing you over a nonviable protofetus. In the pursuit of the 'right' people telling the 'wrong' people what to do, and in the pursuit of keeping the 'wrong' people from telling the 'right' people what to do, anything goes. Hypocrisy, lies, crime, election fraud, subverting courts, coups, false patriotism, false piety, terrorism, even outright murder... anything goes.
Know the enemy, spread the word to your friends and family (and maybe further).
All human lives start out as piles of cells... but not all piles of cells can become human lives.
This is my one concession to contributing to this argument. There are pregnancies that aren't viable. For some fetuses, there is literally no way to make it so that those fetuses can live to become infants. Therefore, these fetuses literally objectively don't have inherent value.
Everybody who's downvoting you, is downvoting you because you are advocating to kill mothers over fetuses that already cannot be kept alive. You're not saying it outright, but by god, you're implying it, because that is what is going to happen if those policies are implemented.
