So Parsifal is the only "FE'er" to even try this one? I mean come on!
Not every flat earth proponent believes in this model. It would be unethical for them to argue in defense of something that they do not believe in.
According to Parsifal, believing in something is irrelevant to arguing in defense for it. Are you calling Parsifal unethical?
I call it much more than unethical, it really is trolling of the worst kind.
Every time you open your mouth you are using the trust you have earned. Every time you use your name, you are building that name into what all others will believe you are.
Parsifal wants us to decide whether he is saying "might" as in "there might be a black diamond" or "might" as in "there might be good weather tomorrow", in just the way he wants. But reality is different: if you talk misleadingly you live with the worst possible interpretation people make of your misleading claims.
Those scientists that Parsifal, Tom Bishop, levee and friends like so much to disqualify live by that standard: every new idea they have is judged based on all their professional history. Or else, ask Andrew Wakefield, Fleischmann and Pons, Charles Dawson (finder of the Piltdown Man).
Science is a collaborative endeavor, where liars and blabbermouths are spotted and blackballed only slowly. That is why they are pretty much blackballed for good, including all their work, not just the obvious lie. We should judge them at least by the same standards which rule the community they consider inferior to them.
