I agree with your comment in general, except this one point: you sometimes absolutely can just ignore it. The instance from the article is one such example.
To be clear, I'm saying it can't be ignored as a parent. Gabe can ignore it, but that usually requires some proper preparation and understanding of how to deal with the emotions it may generate when someone says it. Hence the parenting part.
All of which to say, you can affirm it by being a dick, but that's not the only way to acknowledge the truth. Nor should we pretend the facts aren't there.
