It's a pretty late hour here in the USA (where I expect most would-be respondents are living), and yet you followup with a smug edit, since no one has met your challenge in a mere two hours:

> As anticipated, this comment is unpopular. However, no one has yet attempted to articulate a criticism

You aren't owed a fruitful discussion, and it's clear you're not looking for one. That's criticism enough, but I'll continue.

> spits in the face of process that has produced every genuine, valuable human insight in history

https://en.wikipedia.org/wiki/Psychedelics_in_problem-solvin... and other anecdotal experiments and experiences seem to indicate otherwise.

> I haven't encountered a single LSD advocate that wasn't conspicuously unstable and self-hating

I'm sorry that this has been your experience. That hasn't been my experience. There are a lot of quiet users of LSD, so given your aggressive stance against it, you're most likely to only encounter the most outspoken/optimistic ones. How about someone like James Fadiman? How is he conspicuously unstable and self-hating?

> we don't say a word when they encourage others to risk everything

Many recognize that not every psychological experience is harmless or positive. I see a lot of people warning of the risk of correlation with schizophrenia, and others warning that a negative experience can do a number on your psyche. It's not for everyone, and not for anyone all the time, and many make the point to responsibly disclose that.
