I'm running an Ideological Turing Test at my blog, and I'm looking for players. This year's theme is sex and death, so the questions are about polyamory and euthanasia.

You can read the rules and sign up at the link, but, essentially, you answer the questions twice: once honestly, and the second time as you think an atheist or Christian (whichever you're not) plausibly would. Then we read through the true and faux atheist answers and try to spot the fakes and see what assumptions players and judges made.
