There's a common trope I've noticed among progressive liberal types. Including, I will freely admit, myself. It goes something like this:
Tattoos and piercings are good; nose jobs and boob jobs are bad. Arthouse films are good; reality TV is bad. Nature is good; industrialization is bad. (Except when you're on your Blackberry or your iPhone, or are checking your email twenty times a day.) Meditation and Wicca are good; megachurches are bad. Alternative medicine is good; conventional medicine is bad. Tai Chi is uplifting and spiritual; cheerleading is sexist and shallow. Anything you buy at Rainbow Grocery will be delicious and healthy; anything you buy at Safeway or the A&P will be tasteless and carcinogenic.
So here's what I think is missing when people in alt culture reject science, or cherrypick it based on their personal biases and whims. (No, it's not critical thinking. That's missing too, but it's not what I'm talking about now.)
