Scott Adams, the author of the Dilbert comic and several books, my favorite being How to Fail at Almost Everything and Still Win Big, named his debating format The Rationality Engine. He calls it this way because he claims that it is "the system for turning irrational opinions into rational outcomes". He applies it to several polarizing issues, those this site tends to label "Politics" and "Mind Killer" and shy away from.
His first application, investigating the gender pay gap, seems to have worked pretty well, resulting in several unexpected conclusions. His second, Who is More Anti-Science? I found to be slightly less impressive, but still producing a rather balanced output.
Now he is applying it to the debate about Assisted Dying. Scott's goal is to have a law passed in California that is similar to the ones already in effect in Oregon and several other places.
Scott will debate Jimmy Akin, a prominent contributor to Catholic Answers.
I am quite attracted to Scott's attempts at hands-on instrumental rationality, and on a rather grand scale to boot. They are very much in the spirit of his latest book.
Currently he is accepting suggestions for questions and links for all sides of the issue. Feel free to contribute.
EDIT: I think adding cryonics to the discussion would only complicate the issue and not be helpful, but that's just a guess.
So? Just because they weren't personally convinced by an argument (because they don't go for arguments at all) doesn't mean they can't legitimately believe they have an argument that could convince someone who doesn't do the faith thing.
It's no different from wanting someone to do X and trying to convince them that X is in their own self-interest. That's probably not why you want them to do X, but so what? It's a valid reason for the purposes of convincing them.
Of course, there is good reason to be wary of someone who isn't giving you their true rejection, because motivated reasoning increases the chance of mistakes, but not giving you their true rejection isn't automatically dishonest.
It means they're lying about their motivation and you give them false respect for it.
The practical reality is that they will use arguments as soldiers in a religious culture war and innocent people are going to be the victim of the practical social consequences of it.
Practical ethics implies practical memetics; if you are faced with a culture war you would do well to remember it's a war, not a benevolent debate in good faith.
