Oh that reddit thread. Very very interesting. Someone else trying to do forensic style analysis with the benefit of actual clinical experience. Which is what one would have expected the defence to do more of.
As to conspiracies and nutters.
Some of us have been forced into that position by direct experience of the system. Some of us had lives devoid of conspiratorial thinking right up until experts swanned into our lives "thinking the unthinkable" and put us in a position where we ended up doing the same thing, only to be told we're just "in denial".
Because if you know, for a fact, you haven't done what you're being told you categorically have, and there is no middle ground or consideration of alternative explanations that actually exist but aren't even examined because "experts" you do end up paranoid. This is what expert medical evidence dogmatically applied does to a person if it's going to alter the entire trajectory of your life.
Even if by some miracle a situation is "resolved" but very very conditionally and with emphasis on the fact that the experts weren't wrong but gracious benefit of the doubt is applied, the damage is done and a person is forever a bit broken. Or very broken. And having to hide it and play nice and normal forever more.
Nutter and conspiracy theorist are almost compliments when you've been accused of far far worse.
