Moralizing Against McDonald's

The general rule of critics is that McDonald's can do nothing right. Some years ago, they insisted that the company get rid of the beef tallow in which it cooked french fries. It did so, in favor of a supposedly healthier oil containing trans fats. A few years later, the activists demanded that it abandon trans fats, which it soon did. How much credit did it get for those changes? Not much. The class of people who detested McDonald's went right on detesting it.
