It's not an error when someone could see what was going on & then was proven absolutely right. That's the opposite of making an error actually.

This is that same shit that the Dilbert asshole did, you don't get to pretend you weren't wrong by saying "no one could have known." Many of us knew. Fix your model of the world so that you will know next time too.

Truth & understanding are discovered when people are free to discover them (when they can ask questions & do what they think is right). The sort of people who want to destroy that freedom (censor people & keep them trapped & force them all down the same path) are always the sort of people that are wrong & don't want to be found out. Stop trusting & listening to those people.
