Well, maybe yeah, but so what?
It’s just practically impossible the completely re-evaluate every belief you hold whenever someone says something that asserts the belief to be wrong. That’s nothing at all to do with “overconfidence”, but it’s everything to do with sanity. The time to re-evaluate your beliefs is when someone gives a possibly plausible argument about the belief itself, not just an assertion that it is wrong.
Like e.g. whenever someone argues anything, and the argument is based on the assumption of a personal god, I dismiss it out of hand without thinking twice—sometimes I do not even take the time to hear them out! Why should I, when I know it’s gonna be a waste of time?
Overconfidence? No, sanity!
