If you have read this post by Aarthi, you've been enlightened on what this site is all about.

Islam.SE has the potential of becoming an amazingly active online community. Think about it. Islam is the 2nd largest religion in the world, and at it's rate of growth, it may be the worlds largest in the next decade. That means that we might be getting a lot of questions, from Muslims and non-Muslims alike. The question is, how is this site going to represent it's users as people, because in my mind, there are only two things that could happen:

1. Users continue to do what is happening now and argue and fight about who's sect is correct. The site gets engulfed in these arguments and we become just another Islamic forum. The worst part of this is, we aren't even supposed to be a forum!
2. We change our habits, as outlined by Aarthi, and start using the site the way it should be used.

What does that mean?

Well, first of all, we have to stop giving people the benefit of the doubt. I have seen way to many discussions in chat saying how a question, which obviously looks like it is going to start a debate, is given the "Well maybe he is just curious" thing, and is let go. We can't do that. That is a major source of our problems. We allow the debatable questions, and that starts a nonconstructive debate.

The second thing we need to address, as was said in the question above, is posts that are asking for judgement to be passed. Let me just make one thing clear, we are not checking credentials at the door. You cannot guarantee that the person who is answering your question has any idea what the heck he's talking about. We are not here to say that somebody's interpretation is right or wrong, because we have no authority to do so. We need to close and delete these questions as soon as possible.

Third on the agenda, we cannot allow posts that are trying to promote a certain point of view or sect. There was a discussion about this before. If you see a question that is specifically promoting a certain sect or view-point, close it. For more info, join that discussion (the link I gave).

Next thing is commenting. Let me quote a post from Meta Stack Overflow:

When should comments be deleted?

Generally, there is very little reason to delete existing comments from a question or an answer. There are a few possible scenarios where comments ought to be deleted, but it is worth noting that these should be few and far between, due to their permanent effect on the flow of the comment section.

• Spam: Though it's hard to categorize what's spam and what is simply a verbose commenter, it's a bit like pornography. We'll know it when we see it.
• Noise: Comments like "+1 .." or "belongs on" can be flagged for automatic removal without the commenter being punished.
• Thread Cleanup: If edits have been made to a question, it could be feasible for a moderator to delete all comments relating to that edit once they're accepted. A comment should be added by the deleter stating what was deleted and more importantly, why. For example:

@all : Comments 1-16 detailing editing discussion were deleted when consensus was reached, to clean up the thread.

If a comment doesn't meet either of the criteria above, then it shouldn't be deleted.

Now, a lot of the +1 comments are not enforced, because they really aren't bothering anybody. But, I see a bunch of comments that, as was stated in the above question, are not educating the author. If you see comments that are trying to start a "comment-war", flag it and walk away.

Why did you just post all of that?

Because that is the source of all of our problems. We are having a tough time getting rid of nonconstructive remarks and posts, because of all of the things I have mentioned above, along with what Aarthi said. If we just use the site the way it was meant to be used, we would be fine. We wouldn't have any troubles.

To end this post, let me give you something to ponder: If you could do one thing, without ruining the fact that this is a Stack Exchange community, that you think would help get rid of sectarianism on this site (just on this site, not in the world), what would it be? Now use that thought, and go make Islam.SE a better place.
