Good question, but I think you already know the answer.
Many people find comfort in the belief that a higher power will protect them in the face of mortal threat. Not sure how they reconcile that with the likely similar beliefs of many of the people who've just died as a result of the disaster...
Unfortunately, proselytising, (often by 'pretend preachers' who get off on the mindless adoration of other Hubbers) is rampant on HubPages. Irrespective of the prevailing disaster level. If these folks would just stand in front of the mirror, and 'adulate' themselves in private, HubPages would be a better place for their absence (imo).
I recently had the temerity to question one such backwoods redneck, clearly a legend in his own little version of the world, whose response was "If it's preaching you want, I've got hundreds of hubs published, and you've only got 5.."
Obviously a better talker than listener, since it was fairly self-evident from my comment, that more preaching was the last thing I wanted. I was hoping for a little humility...
To be honest, I don't really care if people want to chat amongst themselves about their imaginary friends; that's as valid a use as any other of a shared platform like HubPages.
It's not my place to comment on the post-disaster messages of hope and resurrection from religious believers, either.
But what does offend me, deeply, are the messages of hate, veiled as 'proof of God's wrath / revenge / anger. (eg the Japan earthquake). Then signed off with the word "Peace".
That's blasphemy to me.
