Yes, Muslim community is a big deal in Islam. But just because a question is relevant to the interests of some, many, most, or even all Muslims does not make it a good question here.
We are a Q&A site about the topic of Islam, but it is important to note that we are not a typical Internet forum, nor are we an Islamic site. Many of the types of questions that would work well on one of those just plain don't work here. As far as Stack Exchange is concerned, questions — real questions — can't just be topics for discussion or solicitations of opinions, neither can they be rhetorical questions to prove a point: Questions here are expected to be practical and answerable.
Political questions, for the most part, do not meet that criteria. They are typically about controversial contemporary situations in which there are very strong partisan leanings; you will not attract actual answers with this question, you'll only attract argument and debate from each side trying to prove why their "Truth" is more correct. The whole thread will just become a popularity contest, which the site is just not geared to handle.
The Stack Exchange model was built under a number of foundational principles, one big one of which is to cut through the noise (e.g. argument, debate, tangential discussion) that already plagues existing Internet fora and just give people the actual answer to their actual question. If you ask a question in which there is a significant difference of opinion (i.e. one that doesn't have an actual answer), especially when it's loaded with rhetoric and bias, all that does is bring the same argument here rather than help anybody.
As to your question in particular, I would bring to your attention the following from our be nice policy:
Don't be a jerk. These are just a few examples. If you see them, flag them:
- Bigotry of any kind. Language likely to offend or alienate individuals or groups based on race, gender, sexual orientation, religion, etc. will not be tolerated. At all. (Those are just a few examples; when in doubt, just don't.)
We are a pluralistic site; "Islam" so far as this site is concerned includes everyone who self-identifies as Muslim, and we are open to everybody. As such, all posts, not to mention all users, are expected to treat others with respect here, whether they deserve it or not. As such, any posts that say — even imply — that any particular group deserve our hatred are not welcome here, nor are posts which are likely to instigate hatred against any particular group.
If you actually have a real question that you need an actual answer for, you can take the time to write it politely and with respect (see also the advice in our help centre on "How do I ask a good question?")
If, however, your post is just thin excuse to call out what you see as atrocities committed by the Saudis (which is exactly what it looks like to me), it is wholly inappropriate here. Frankly, the only reason I haven't already flagged your post as offensive and had it removed completely was because you're relatively new here and I'm willing to give you the benefit of the doubt.
