There are two existing religious sites on the network: Judaism (Mi Yodeya) and Christianity (Christianity SE). These are both very broad categories, containing multiple viewpoints. How do you define a "Jew"? How do you define a "Christian"? The sites have wrestled with this, and settled on very different answers.
Mi Yodeya has settled on interpreting orthodox Jewish thought. All answers refer back to the writings of various Rabbis, and all questions are expected to be within that framework. That means that Reform Judaism is barely on topic.
Beta Q&A site for those who base their lives on Jewish law and tradition and anyone interested in learning more.
Christianity SE has taken a different tack, possibly because Christianity itself is more fractured. All Christian traditions are on topic, but questions must explicitly mention which traditions they're interested in. Answers from other traditions are then off topic. This avoids a vote contest between different branches of Christianity.
Personally, I prefer the path the Christianity site has taken, but it's not hard to see that Mi Yodeya is more "academic". Whether or not that's a good thing, and to what extent a site for experts should be "academic" is, of course, open to question. And, of course, the difference in cultures between the two sites might be caused more by differences in religious attitudes than by differences in site rules.
So, question: How are multiple viewpoints handled here?
