I was just about to point this same thing out. Asking good questions works so much better than trying to tell them how they are wrong, so after validating them start questioning their logic (or lack of logic). I actually learned about this in therapy to assist in communicating better with my wife (who has a personality disorder) and then later realized it's the Socratic method. Validating the things you agree with is still important too, but this article is missing the second part where you question their claims.
