Wow where do you shop, prison? That sounds terrible. I love shopping at the grocery store. I love food in general though, and buying it makes me happy.
I think there are some various definitions for the word jerk. I think it stems from the term jerk-off aka masturbater. Masturbation is healthy, it adds years to your life if you orgasm regularly. If you don't always have a partner, or if you partner isn't always in the mood, I think its a healthy alternative. So in conclusion buying organic does make you a jerk, because being a jerk is a healthy choice, just as choosing organic.
That's why I shop mostly @ the farmers market or grow it myself
