I am involved in a number of communities that engage intentionally, even sacramentally, with psychedelics. The amount of sheer bullshit they continue to promulgate on that matter, about which I consider myself advanced-lay to burgeoning-expert, is staggering, and is sufficient for me to be default skeptical of anything else they might have to say. When you lie to me about things I know something about, I'm obligated to trust the rest of your oeuvre somewhat less, aren't I?
Finally, I said nothing whatsoever about the conclusion of the paper under general discussion. In point of fact, I generally agree with it.
