I haven't gotten through the whole thread yet, but this is my favorite response from the original poster so far:
"All the shemitah is is a cycle, we are all governed by them, and this is just one of them. There are others mentioned in the bible, namely the 666 or beast cycle."
It's like one of those 'Billionaire warns of dire finanical crisis' ads you see at the bottom of click bait sites but in reddit post form.
