> The self-proclaimed "pro-life" movement also strongly supports the death penalty, strongly oppose any sort of financial aid for poor children, are typically strong supporters of the military and violent intervention, unconditionally support the police in police violence cases, support corporal punishment of children etc..
This is an incoherent straw man caricature of "the right". Unfortunately for us all, there are tons of people in every side of politics who hold incoherent sets of positions. They're the "sound of a potato rotating" [0] kind of folks.
By "incoherent" I mean that I agree with you that it doesn't make sense for somebody to both be "pro-life" and also support the death penalty. But there are people who hold positions that are at least internally consistent.
Why bother crafting arguments against the former (where you'll gain little if anything from winning) when you could against the latter (where you have a chance of changing the minds of a lot of people, if you make a strong argument)?
