I recently closed a question which raises an issue we've only just been skirting around.
Remember that the purpose behind an "Islam Stack Exchange" is to build a compilation of knowledge about the subject of "Islam" — You cannot reasonably hope to cover any possible questions of interest to Muslim *users*.
So why does this matter?
Sometimes it is easy to forget not to treat this forum like a general support group… covering anything of interest to the Muslim community. Some questions are only tangentially-related to the subject of Islam. Try not to turn this into a issues or political forum, or a place to ask "What do Muslims think about [X]?" We are not not here to discuss Islamic countries or their conflicts nor are we here to solve the world's problems from an Islamic prospective.
This is a site about the subject of Islam — and creating a great canonical Q&A resource for those who come after.
Staving off these "extra curricular topics" is an issue we've dealt with for a very long time; wow going back for at least 3-4 years. It started as the "Favorite soft drink of programmers" problem on Stack Overflow. Yes, Stack Overflow is a site for programmers, but you could not reasonably expect to form a Q&A site around any question of interest of programmers. The site would soon become about anything — all you have to do is append "…for programmers" to the end of any question and, poof, it becomes on topic.
The whole point of these sites is to form a community around specific topics. There's nothing more toxic to a community than not being able to set boundaries around it. If you allow discussing everything, you have allowed discussing nothing. That's why we shy away from these extra-topical questions.
When the work of Q&A is done, we have a proverbial 3rd place to chat with fellow Muslims about these other topics that interest you. But a focused Q&A community cannot form around “let’s just talk about everything we're interested in." It won't work.
