Again, religious pro-lifers refuse to have any ethical or philosophical discussion whatsoever. They are absolutists who are unwilling to entertain a utilitarian viewpoint or any other justifications for abortion. There is no "middle ground" with them.
And why have you chosen to portray the most radical and unreasonable of all your numerous opponents? It's not exactly "straw-men" because these people exist, but looks pretty similar to it.
Because they are the base that the republican party answers to. They are the Supreme Court justices who are members of the Federalist Society who have been playing the long game to overturn Roe and other decisions. I'm portraying those who have actually been doing the mechanisms of overturning Roe. This isn't some hypothetical debate, these are organized groups mobilizing to enact change.
Only if you're an utilitarian. There's perfectly good reasons not to subscribe to this moral philosophy.
