yes you did, you said everyone that likes the grateful dead 'smokes pot to pretend to like their shitty music'. im pretty sure that generalizes everyone that is a fan of the grateful dead, and on top of that you called it shitty music which isn't really necessary.
off the top of my head... look at the mods and (punk)rockers, tight leather clothes piercings crazy hair, hip hops all about baggy clothes and doing things big, during the counterculture movement with the dead and all those bands in sanfran it WAS about tye dye shirts and all that crazy hippy clothing, there IS quite a connection between peoples lifestyles and the music they listen to, im not going to dig into my notes from way back to prove it to you, but don't say that there is no connection there because there certainly is.
