You must not understand the concept of burden of proof.
—Rossoya mentioned Extinction Rebellion and, in context, his comment implied they may have been responsible for setting fires.
—I said as far as I know, their tactics have nothing to do with these fires. (Because none of the sources I’ve read on these wildfires have said that they were responsible.)
—You called me dumb for saying that.
—Okay, now ball’s in your court to counter my assertion that there’s no evidence that Extinction Rebellion was responsible. Otherwise, my statement stands. Put up with the evidence or shut up.
(You could say that in support of my proposition, I cite every single article written about the Australian wildfires that doesn’t claim that Extinction Rebellion was responsible. Which is all of them, to my knowledge.)
