Would suggest that this particular subject is so sensitive to the welfare of a very large number of people around the world that it be suspended. The usual level of rhetoric that occurs on these pages may end up being consequential to actions by others. This is a dangerous time, and a dangerous situation, and those in charge have shown a propensity to use "intel" from any source, irrespective of veracity.
What you are suggesting amounts to censorship of this subject, which by the way is something that the news websites seem to be doing by closing their comments sections on this subject.
I would suggest that sites like this are a fantastic source to disseminate real information regarding touchy subjects like this that are not moderated by the media outlets, all of whom show an overwhelming desire to appease Iran.
I don't suggest that I know whether or not this aircraft was shot down or had a catastrophic failure of some sort, but it does a disservice to the people who died on that flight to assist in hiding the truth - and that begins with censoring subjects related to it.
