I assume you're asking because you're surprised, not because you want comments to be closed.  

 I get really frustrated when I see comments closed whenever there is a story that has anything to do with Islamic issues.  On the other hand, in the rare instances when they do allow comments, I often find more useful background information and insights from people's comments than from the standard, official, sanitized MSM accounts of events.

Of course, I also choose to ignore comments from those people who are driven simply by fear, bigotry and ignorance.  As a responsible adult, I like to be given a choice to participate or not in a healthy debate on such critical matters as terrorism.

Let's hope they keep this forum open.
