Have you ever heard the saying: "Put your money where your mouth is"? It applies here! Have the giver of this "advice" hand you a check for say, $5,000 with the promise you will deposit it a bank for six months. If no engine damage is apparent by then after having run it 2 minutes without coolant, he gets his money back, with any interest it earned.
Running without coolant for a minute or two will result in localized hot spots forming, which may result in distortion of the block or head. Keeping the coolant in the engine results in an equalized warming up of the entire engine, which is healthier for it in my opinion. So what if it takes a little longer to reach operating temperature??
