You mean, by posting a one million dollar paranormal challenge (https://en.wikipedia.org/wiki/One_Million_Dollar_Paranormal_...) that offered a million dollars to anyone who demonstrated a paranomal effect in scientifically valid laboratory conditions? And who opened the contest to over a thousand candidates, all of whom failed?
Sorry -- that's not how a scientist defines irrationality. In essence, Randi's challenge was, "Put up or shut up." A thousand put up, none succeeded, and since then they won't shut up -- which, in fairness, is their right. Meanwhile, no rational person misses the irony that the complainers produce everything but evidence.
In discussions about, for example, dark matter, personalities don't matter, because we have evidence. By contrast, in debates about the paranormal, personalities are everything, because of a perfect evidence vacuum.
Remember, when you bring up Randi, you're acknowledging a spectacular evidence vacuum. The greatest amount of scientific eminence is trumped by the smallest amount of scientific evidence.
