It’s common sense that eating a cheeseburger the size of your head throws all intentions of healthy moderation out the window (“Dietitian at vegan advocacy group wants warning label on Michigan team’s huge, new burger,” April 1). But if Michigan’s minor league baseball fans need a reminder, there are far better people for that job than an antimeat guru like Susan Levin. Levin’s organization, the deceptively named Physicians Committee for Responsible Medicine (PCRM), is a vegan-activist group with less than 4 percent actual physician membership. More than two-thirds of its funding comes from vegetarian restaurant owner Nanci Alexander, the wealthiest save-the-cows activist in the country. No wonder PCRM wants to remind Whitecaps fans about the difference between a 4-pound burger and a salad.
