As a kid, I didn’t exactly choose to be a vegetarian. It grew out of my extreme pickiness combined with my parent’s limited cooking skills. Meat was one of many broad categories of food I just didn’t like the taste and texture of.
Of course, by the time I was calling myself a vegetarian in high school and college, the label itself seemed to draw other meat-skippers into my life. Most of these friends had better reasons for their dietary restrictions than I did, and I learned a lot about those reasons just by hanging around them. I learned about factory farming, antibiotic overuse, and water waste. I felt pretty good about not eating meat.
