This. Conspiracy theorists, especially, don't debate. Their arguments are full of fallacies and they keep moving the goal posts. It's impossible to debate them cause they'll keep changing the topic with redirection.

We need to stop allowing them to do this. Call them out on this, point out the fallacy directly and emphasis that they aren't good at arguing/debating, that they're good at misdirection/moving the goal posts.

Their entire tactic is to keep the opposing side back-peddling to cover new information based on fallacies that the conspiracy theorist randomly throws out there.
