there's a long history of these on Christianity.SE - a lot of folks thought they were fine when the site first launched; it didn't take very long for the cracks to appear though:
1. anyone can self-identify as "Christian" - you don't have to pass a test or show ID
2. anyone can have any opinion on anything
3. therefore, anyone can ask a question about anything or anyone if these questions are allowed.
The rules were eventually tightened up to be closer to "you must ask about the topic, not the people".
