Here's the problem; I *have* heard all of their arguments before. There's not going to be anything novel here. This is pretty well-trodden ground.
That's not a formal proof. It's an allocation of my time and resources. They can generate new conferences faster than you can refute them. "You can't dismiss me until you've heard MY version of this old argument, and you can't know that it's the same thing until you've heard it" gives them an infinite lease on my time.
So I'm not going to "hear them out". Somebody, I imagine, will, because an odd number of people seem to enjoy re-fighting this. And if they manage to derive an argument with a shred of merit, I suspect it will get back to me. If it takes a long time to do that, well, that's how it is with all ideas. Valid ideas stand the test of time; truth lends them durability because it can be independently re-discovered.
That means that I don't have to give them any time to consider their ideas. And for them to insist I do is dishonest. Any argument they might have to make has to begin with "OK, I understand why you consider the rest of my ideas idiotic, and your reasoning was sound," because it is. Until then it's just more deranged babble.
