DISCLAIMER: This mostly applies to Gen X/Gen Y hippies, sometimes called "Neohippies." I'm not necessarily talking about older hippies, though if you see yourself or your older hippie friends in this, that's not my fault. That said, some older hippies seem to have had a genuine committment to changing the world and really tried to do things in effective ways. Props to them, but I don't see hippies in my generation doing that really at all.
My thing against hippies dates back to at least my college years, though I have certainly had experiences since that have confirmed it.
There was an entire dorm full of hippies at my college and my experiences with them were mostly negative. Probably the most dramatic of these was during my senior year. I was president of the "Egghead Dorm" where all the science majors lived. I had won on a platform of "Vote for me and we won't have a dorm-wide party. We will buy a hammock for the courtyard and some picnic tables instead." I had a meeting every Sunday night where I would gently dole out advice to the suite leaders under me, basically running things under a "don't be an asshole' shall be the whole of the law" sort of philosophy.
Our dorm was non-drinking, the only non-drinking dorm on campus, and there was a tacit agreement with the administration that we got away with a lot of minor rule violations but the campus police wouldn't walk through often because we were slighly out of the way and we were so darn well-behaved on the big stuff.
Then the administration decided that since our dorm was SO good, that they should move a few of the biggest hippie troublemakers into our dorm. Maybe that would make the troublemakers behave.
Of course, it didn't work that way. Pretty soon, a solid quarter of the science majors were partying all night and the dorm always smelled like pot and nobody could study. Every meeting was a mix of self-righteous hippies bitching at me because I was trying to enforce the rules, sometimes assuring me that if I just used drugs I wouldn't care so much, and appalling things like a guy in a wheelchair saying "PLEASE make everyone be a little bit more responsible with their glass bottles. I'm getting broken glass caught in the treads of my chair and it's cutting up my hands!"
So basically, my sweet little meetings became hell. Five years later, I would read the Tipping Point and start to understand what had happened.
Since college, I've continued to see evidence that hippies tend to have certain qualities that drive me crazy in a human being. I tend to think that people who have these qualities are drawn to hippiedom, which reinforces them. If a self-declared hippie does not have these qualities, I can get along fine with them, it has happend before.
SELF-RIGHTEOUSNESS-- There are many decent examples of this, probably the best being the Andressohn case in Florida. These were hippies who were raising their five children on a raw food diet. One died of what appeared to be malnutrition.
That article doesn't have much on it, but the parents' defense was that the baby had a congenital disease which they didn't know about because they don't believe in the medical establishment.
Had they taken their kid to a doctor when it only gained a few ounces in its first six months of life? Of course not. A doctor would call that "failure to thrive" and start running tests, but they knew better than the medical establishment. They're hippies. So they treated the kid with wheatgrass enemas. As far as I've read on the case, if the parents even understood that they could have saved their baby's life by taking him to a doctor, they never acknowledged it. Their way was the only way.
The prosecution contended they starved the baby to death.
Needless to say, several hippies I have known have brought this case up as an example of the horrible discrimination raw foodists face. When Christian Scientists do this kind of thing, I hate it too. But at least with Christian Scientists they are doing it for religious reasons. For hippies, it's about showing off that you know better than the establishment.*
Do most hippies take it this far? Of course not. But the number of defenders this couple has, and the amount of "anything mainstream must be bad. I always know better because I'm hippie" attitude one sees other places is enough to turn me off.
POT SMOKING--- People who smoke pot smell really bad and don't seem aware of that. And if you smoke up every time life gets hard, you become a little kid emotionally who expects the world to revolve around you because you don't have the maturity that dealing with unpleasant experiences like an adult brings.
LAZINESS AND SELFISHNESS- Hippies like to complain about politics, but when they do anything about politics, it's usually something pointless like a protest march. (And nothing makes a protest march less effective than a plurality of hippies. People going by look at them and think "This march isn't full of people like me. It's just a bunch of hippies." PLEASE people, if you must attend a protest march, wear your dockers.) The hippies I have known like to bitch and moan but are almost never up for anything actually effective because effective things involve sustained effort. IMHO, they like to bitch more than they like to improve things.
And LOTS of them live off their capitalist parents.
SPECIFIC TOLERANCE: "You can believe anything you want to, as long as it is what I believe. If you differ from my beliefs in any way, politically, nutritionally, morally, etc, then I have the right to lecture you endlessly. Because if you really understood the world, you'd see things my way." (I thought of it as a part of self-righteousness, but someone just emailed me making the case that this deserves an unattractive quality category all its own.)
*Clarification: If ADULTS want to go and live off in the woods free of capitalism and the medical establishment, they have my blessing. But the ones who break a leg, then call for capitalism and the medical establishment to send a helicopter, get fixed up and then go back to bitching about capitalism and the medical establishment suck.
