Not exactly going to disagree with you there. Just felt it was an important question to ask considering the rigidity of their comment.

I'm not the original reply, by the way. I think psychedelics can be fun and extremely liberating/relaxing. But they have not given me any significant personal, scientific, literary or other insights.

I find that whatever insights, they’re personal. But their general effect humbling our egos. I find that to be of great use in a selfish narcissistic society we’re living in. I remember after having an LSD trip with good personal insights I got home and had cathartic session of sobbing. It felt absolutely great to do something I rarely do. Last time I did this was more than 15 years ago and feel that I’m still drawing some essence from this experience. Perhaps if I find myself stuck or at crossroads I’ll give it another go.
