Now you're just being difficult. If you don't know why it just might be healthier to drink a glass of 2% vs a glass of whole milk, you're just trying to start an argument. For you, who eats a lot of greens, of course there's nothing wrong with it. However for most people who don't eat that healthy, the option for a lower fat content milk is there. And if you are really having trouble finding whole milk, you're not looking hard enough. I agree with your point that many people foolishly use these "diet" foods to overeat, but there's nothing wrong with healthier options.
