"No, I said there'd be some mass die-offs within 6 months."

Okay, define "mass die offs" right now. And they'd better be for humans.

"if an entire city DOES burn or flop over dead, would that constitute enough proof, or would you still make up BS to try to hide this reality?"

Depends on the cause now doesn't it?

If there are mass riots which cause mass fires, something that has happened in the past, then no, that isn't proof of your claim.

If a flu outbreak kills half a city then you don't get credit for that either.

Proof is very simple:

Measurably high levels of hydrogen sulfide.
