GUEST is no more objective here than anyone else.

If it's true that none of his acquaintances ever ate a mushroom or took a toke in hopes of some kind of spiritual enlightenment, he just wasn't in the right place at the right time. He (or she?) is relating personal experience and trying to claim the authority of objective "truth," and it just doesn't wash.

I find the demand for additional "evidence" or "proof" that hippie musicians suffered from excess idealism to be absolutely laughable and not worthy of further comment.
