Imagine you're standing on a beach when the water recedes very very far. Do you yell "tsunami" at everyone in range as loud as you can? Or do you go up to each of them, strike up a conversation, and slip in "what are your thoughts on high ground? Personally, I think it's a good policy."

They sperging out because they're in a perpetual state of thinking that we're already teetering on the point of no return and they're panicked. If that's rational is an exercise left up to the reader but that is why those posts go the way they do.
