I suspect that there are as many ex-hippies in the Tea Party as there are occupying Wall Street. Maybe more, actually.
Many hippies were of the drop-out, leave-us-alone, anti-establishment libertarian sort, and not really leftist (in the normal sense) at all. And many of the young leftist activists of the 60s were not at all hippie-like.
Of course, by the end of the decade pretty much all of us looked like hippies. That was just the fashion of the times. I liked the clothes but wasn't about to go join a commune in Montana.
Nor smoke pot (I always much preferred a good claro panatella) for that matter. Some of us weren't into dropping out and complaining about 'the man.' I think that's what the Tea Partisans are still doing.
Maybe it's time they grew up too.
