I was just inspired by the great sentiment at the "Christianity.SE vs. Survivor" post. The writer said it was not useful to kick people off the island for not meeting your standards for deserving to call oneself a Christian. There is kindness, inclusiveness, and great pragmatism for running a secular site.
Can we have all three of those for people with no identifiable perspective? I've done a great deal of studying of the writing of Luther and John Paul II. I served on the Council of a Lutheran congregation for six years. I teach Sunday School at a nondenominational church now. The pastor was ordained in the Conservative Baptist Fellowship of New England. I write my own Sunday School material and occasionally send it to the pastor, and he's never complained.
When I hear that requirement, it sounds like this site is for people who will give answers that make the tradition they are in look good, not for well-read people who can give factual answers.
