I have made a point - that he knew, or should have known what he was getting into. If he failed to do that (which I don't believe) then he should not have trusted his own judgement about what was or wasn't constitutional and what should be leaked - because the vast majority of what he leaked didn't expose any wrongdoing whatsoever.
My thesis is not tha the joined with the intention of leaking secrets. My thesis is that he joined up thinking it would help him straighten out his sexual identity issues and when it ended up making them worse it's unfortunate (largely for himself) that he didn't seek a medical discharge on basis of his gender dysphoria and the severe stress it was causing him. I don't think he's an inherently bad person, but if you're going to carry a top secret clearance you have to be aware that that's some Serious Business.
Do you have any experience with people?
More than you seem to imagine. It's because I've spent so much time out at the fringes of society that I have so little patience with this infantilist bullshit. Like Manning, I left home and (broken) family at a young age to make my own way int he world, instead of going along with the crowd on the conveyor belt. I sympathize with him, but I also think that respecting his right to make his own choices also involves investing him with the responsibility for the outcomes of those choices.
I like what I see of Manning, but think he made some catastrophic mistakes that's he's going to be paying for for the next few years. Your view of events is predicated on him being a helpless automaton that joined the army and earned a top secret clearance without understanding what any of that meant, which is to deny him agency for his own actions.
