The problem with your initial post is this/these IMO:

1. No one on the internet gives a crap.
2. at least 90% of people are agnostics, deists, or atheists.
3. Even people claiming to be Christians are in actuality Deists like Jefferson. The type of people that can remove what they want from the Bible and believe "their" God doesn't do that or want/expect that from them.
4. When any of those apocalyptic events happen no one will be here to say you were right, remember you posting this, or otherwise.
5. After it happens people will be worried about how to get their money, trade, steal, get stuff for their children; or worried about the 'aliens', the Russians, the Terrorists, or whatever other snark or bugawug is out there.
