I don't know anything much about modern hippies (I thought the rednecks had shot them all by now).
But back in 1980 when I was obsessional about getting the social thing right, they did me a lot of good. Their ethos seemed to be total acceptance of any human being, which contrasted favourably with the cold-hearted ways of "straight" society. For a time they were the only people I could really open up to. There was a commune just down the road with a policy of leaving the door permanently unlocked because they felt they'd rather be burgled than accidentally exclude a needy stranger from their home. Any food brought into the house was common property. Everybody was so incredibly friendly, with no ulterior motives apart from they liked being that way.
But labels can be misleading. Very few of those people would have called themselves hippies. Like myself, if asked, you'd get an answer like "well I'm just me really, a bit of hippie, a bit of anarchist, a bit of socialist, a bit of surrealist, a bit of Reichian, but mainly I'm just me." What they had in common was that they all felt that mainstream society was a dystopian mess that wasn't worthy of their participation, and they were proud to turn its rules upside down and to blow raspberries at conformity. Nor were they wimps - a group of feminists trashed the local porn shop late one night, simply out of principle.
I don't say it was the answer to everything, but I'll never forget what they did for me. They built my self-confidence when the rest of the world didn't give a damn about me. If everybody was like them, my life would be sublime.
