Is Dairy a Food Group?

How do you get a nation of people, who were raised and brainwashed to believe that DAIRY is a food group, to open their eyes to nutritional truth?

Naysayers: "Nevermind what you purport, Lisa, Dairy IS a food group. . . that's what we were TAUGHT - so it has to be true, and we don't intend to eliminate a whole food group from our diet - so go some where else with your 'health is in plant foods speech.' We're good. We'll survive."

And according to these deceptively erroneous food groups, if fruits and veggies are carbs and grains are carbs, what are low/no carb dieters eating?
