Seriously, you can't win. Here you have an actual former NSA employee giving a first-hand account of his time there -- and not only his account doubted for no reason other than failure-to-comply with known-biases and unverifiable journalism, but some guy is now providing psychological analysis of him as well!
Some know-nothing armchair psychologist who read the NYT is telling this guy -- who has made an honest effort to be utterly transparent -- that he's cognitively dissonant and that comment is going to receive a hundred votes because it makes people feel good about the things they think they know. It's not truth, just an exercise in mass delusion.
