I don't think a little fear is unreasonable (and it's probably at the root of any "offended" reaction). I've struggled for years to get into jazz in the way that I perceive jazz enthusiasts to be "into jazz," and maybe I never will. But I take it as an encouraging sign that I'm finally struggling less with Grateful Dead jams than I did for a very long time. (Taking in lots of '73 second sets has helped.) Maybe there's hope for me yet. Ultimately, it's a process, we're all on a continuum, and we can adjust our placement on said continuum with some desire and effort. EDIT: But yes, the idea that one has to be high to listen to the Dead's more out-there excursions is dumb. It says far more about the person who has that idea than it does about anyone else.
