How To Win Friends and Influence People doesn't actually advocate never trying to convince people of an opposing viewpoint. Carnegie argues that you'll never be able to convince people of something by correcting them directly, but that you can persuade people if you express genuine interest in their opinion, listen well, ask questions, and allow the other person to save face by presenting the correction as something they came to on their own. Whereas, if you correct someone directly, no matter how solid your facts, they are more likely to feel attacked and double down.
