DingusKhan and Pagan too, of course:
Here's my definition of a hippie:
Someone who really sees through the falseness of social and cultural phony ass bullshit.
Someone who is incapable of conforming.
Someone who expresses authentic feelings and gives the middle finger up to playing phony games in order to conform.
A real hippie isn't a particularly hostile person, so this may be where they part ways with punks...
Someone seeking knowledge and enlightenment. (This was the problem for me back in the 70s: the damn hippies I knew bored me to tears; all they could talk about was drugs.)
A worshipper of nature.
One who serves the goddess Cannabis. This includes cultivation, intelligent, geeky discussions with other servants, and use of the sacred herb.
A hippie is not:
Someone who dressed like a hippie. Lots of idiots did that in the 60s-70s.
Someone who abuses drugs.
Someone who's going thru a phase, but will end up working in a corporation or on wall st.
Someone who's mean to others, like charlie manson, rip.
