To the urine comment.
You don't have to drink your own urine. Simply toasting them in the oven will convert the chemicals safely. You pour the juice that comes out back over the mushroom.
Anyone preaching the need for drinking urine is somewhat unrealistic in todays society. It used to be done because the chemicals are converted in your body, and stay intact in urine. The upper class individuals in town would eat the mushrooms, the lower would then drink the pee and get the same effects. Yes, it's yucky, but it's not the society you were conditioned to. Stranger things have happened.
It's entirely possible to have amazing experiences with this. You needn't worry about liver failure. If you're picking cyanescens you've a much higher chance of slipping up and getting something poisonous (although no chance if you know your stuff, naturally) than with Amanita. There is no other mushroom you could mistake it for.
If he wants to preach about an amazing, often overlooked experience he just had, more power to him. He's just getting the word out that theres much potential. Obviously you guys can make your own decision.
I think mushrooms are something worth being obsessed about for some reason. But everyone is obsessed with something, and nearly everything has someone who is obsessed it. I agree that going as far to think that mushrooms in general are the parts that hold together history is a bit nutty though.
Something is not simply a wonderful drug because it's in a mushroom. Obviously, many will kill you. Muscimol has potential though. And I don't believe Wasson thought there was much to Muscaria.
Comparing Amanita to Datura is a bit off. They do have the common factor that the majority find them unpleasant, but in very different ways. Amanita users could find themselves in for a night of stomach problems, uncomfortable feelings, and disorientation. Datura users could find themselves temporarily blind, psychotic, delierious, harming others, or themselves. Yet there are 'responsible' ways to use datura too. It's a great too for shamans. That doesn't mean I'll ever try it.
