I don't know how true the latter part of that is (the former is definitely true) but people like that aren't going to be disabused from their beliefs regardless of the criticism, it's religion at that point.
All I'm saying is if people want this to be taken seriously, and approached credibly, they need to stop taking the word of people like Lue Elizondo uncritically. We don't know that any of these people actually know anything about anything. We do know they can't or won't prove anything beyond a reasonable doubt. We also know the proof they do provide, when they choose to provide it, is often unreliable, circumstantial or outright fraud. That should be more of a red flag for people than it seems to be.
