Leah Anthony Libresco is looking for partners and judges for an ideological Turing Test on Christianity and atheism:

I’d like to put my money where my mouth is and play in an ideological
Turing Test against a Christian blogger. We could both answer a
selection of questions posed by Christians and atheists or we could
each write an argument for and against the side we support and then
briefly rebut the two arguments the other one had produced. I’m
flexible and open to suggestions.

If the test happens, I’ll definitely blog the results.
