Re: No
mdlm... I think you are nitpicking here. The point is that a raise both gives you information about your opponent's hand and challenges you to call one more bet (at better pot odds, as you have noted). Preflop, the information you gain about other hands almost never causes the call of one more bet to become incorrect. Postflop, a raise can tell you that you are hopelessly behind and therefore should fold. There is almost no situation preflop where a raise can tell you that you are hopelessly behind.
