I do not judge anyone without walking in their shoes.
The inability to judge someone's credibility for trafficking in for-profit, paranormal, video conspiracy theories leaves you unable to judge not just this person's claims, but a vast range of other exaggerators, charlatans, used car salesmen, and politicians.
It's not about judging them personally, whatever that means. (I mean, we're not God, right?)
It's about trusting claims they are making about things that could and should have evidential bases.
I'd trust Tarun: A British Audiophile in a second over this guy.
