I agree, to a point. Sometimes mods can get a little gung-ho keeping things on topic. Not just here, but in most any forum covering any subject.
Any subject, no matter how much you're into it, can get a bit stale if that's all you're allowed to talk about. A little off-topic discourse can act as a bit of a, break if you will.
With that said I think certain things are just better off left alone. For me this is one of those conversations since, to me, it does little except to feed into fear, and has the potential for a negative impact. Fear of things that may or may not happen, basic on little more than conjecture, and a lot of that driven by individual fears which themselves may have no factual basis.
Aaaaanyway, how 'bout that weather?
