The statement (which you refer to as a claim) is flawed for the reasons you gave. Your rebuttal was excellently worded, and was logical. But, there is a major flaw with your rebuttal : the people who make the claim are not logical people. The only people who can understand your rebuttal are logical. You will spend your energy preaching to the choir, because the people who make the original claim will not stay and listen to you. It was really nice to read a well-stated post.

Modus Ponens:\nIf is true P, then Q is true.\nP is true.\nTherefore, Q is true. \nExample:\nIf you buy today, I will give you a 10% discount. You have agreed to buy today, so I will reduce the price by 10%.\n\nModus Tollens:\nIf P, then Q.\nQ is false.\nTherefore, P is false.\nExample:\nIf there is smoke, there is fire. There is not fire, so there is no smoke.
