There are two reasons I think that we should not have these questions:
These questions look like boat programming questions. The Meme of Boat programming came from a question which was asked on stackoverflow as to how to program on a boat (how much fuel does one need to run a laptop, etc. It is hard to see on the screen dump and the original question was deleted).
What is the problem of "boat programming"?
It has nothing to do with programming!! It may have to do with sailing, it may have to do with laptops, but it doesn't require a programming expert for an answer. It needs a sailor.
So too with "Comparative religion" questions. I would be OK if someone asks here "Why do you pray five times a day on Yom Kippur and asks on Islam.SE the same question and compares the answers on his own. However, asking here "Do Jews and Muslims worship the same G-d? If so, do they understand G-d the same way?" is
- Counterproductive - most people who are experts in Judaism aren't going to be experts in Islam
- Goes against the purpose of this site - "Jewish Life and Learning - Stack Exchange is for those who base their lives on Jewish law and tradition and anyone interested in learning more." These questions aren't 1. "for those who base their lives on Jewish law and tradition" as neither Jewish law nor Jewish tradition discusses Islam and 2. "anyone interested in learning more" as these questions don't further Jewish knowledge at all.
- Pushes away experts - experts would gravitate to websites which discuss technical questions in their field. Unless these questions are discussed in Jewish books (in which case they should be welcome), these are not the types of questions experts would want to see.
I mentioned Islam here because one of the questions mentioned by the OP was about Islam. I am of the same opinion if the questions being asked are about any other religion.
