Some take that fear of the inexorable and use it to make believe that they are a higher caste, prechosen to sneer at the non-worthy, non-elite/elect. Others take that to speculate about the methods of Ragnarok and the time. And still others posting pictures of their teeth. The weirdest pictured ones believe in God as an alien UFO diviner using bio-genetically created robots posing as aliens, but who are actually controlled by demons (yes, that's what they believe) and believe that Jesus Himself was an alien. Others say Jesus was just the Archangel Michael etc. etc. -- the permutations and combinations in which man tries to fill the void due to their revolt against God's community are myriad and strange.
You make an interesting point. Rapture theology does indeed appear to play to a sort of longing to escape the travails of this life while lording it over those who are left behind to suffer. There’s a longing for the end of life’s sufferings in all of that. There’s something unhealthy about a continual fascination (to the exclusion of much else) with the end of the world, and a flight into a fanciful and completely novel reading of ancient texts. It’s a sort of flirtation with death, really. It’s interesting that Shi’ite Islam has an analogous end times narrative, motivated I think by the same longing for the end.
