> Things in the realm of anti abortion and pro death penalty break down when you get down to the root of things, which is free will and innocence of the unborn soul
...no?
The essential point of steelmanning is understanding your opponent's perspective, perhaps even finding a better argument for it than they have, even if you disagree with them.
It's perfectly possible to do that even if you think their position is nonsense.
Sometimes you may even find that your perception of their arguments and ideas is incorrect.
> There is literally no evidence for an immaterial soul
There's no hard evidence, but there are things that are, let's say, weird. The hard problem of consciousness is one, and the steady trickle of reports of veridical observations from medical staff treating unconscious NDE patients is another. For that matter, NDEs themselves are odd in absentia the supernatural.
I don't expect people to grant souls or the supernatural based on those things, but they're certainly observed phenomena that some people interpret as evidence for those things.

If you're referring to other evidence, I'd love to know what it is.
