That literally CANT be how we define living human beings. Babies can’t survive independently for years after being born, they are unquestionably a living human. Or an accident victim on a ventilator... they can’t survive independently and are again clearly living humans. Millions of people rely on assistive care and are living humans.
It’s interesting that this only applies to unborn babies. “My body my choice” right? But a born baby has needs you to use your body to take care of it, you literally can’t choose to not get your ass out of bed and feed it, or choose to leave it home alone and take your dumbass out, so why can this “parasite” remove your choice only after it’s born?
