Some green parties tried the same nonsense for a while, though I think they all admit to being left by now. The argument was that they'd work independently of party blocks with climate as the only issue.

Yep, it's called Fish Hook Theory:

Wasn't fascism originally about being neither right nor left, but then it got sort of absorbed (or bought out) by the right to combat the left? Thats atleast how I've understood it, and of course there is so much more to fascism than that but thats just how i'd summarize it
