I'm sorry to hear that you were hurt by psilocybin and other drugs. Unfortunately I think a recreational drug culture is ill equipped to understand and manage the hazards of powerful hallucinogenics drugs, and that too many people are left with bad and even traumatic experiences.
But doesn't this go both ways? How do you expect people who found a profound benefit from psilocybin not to discuss their experiences? I can understand advocating for caution, absolutely, but you're implying in your earlier comment that you believe they're deluding themselves. Why would your experience invalidate theirs?
