From the perspective of most people on this forum, that post really oughta be the end of this discussion. It addresses every salient point. That said, there are people (here and elsewhere) tying themselves in rhetorical and bad-faith knots, and it's a really bad look for the profession.
Meh, some of the anecdotes seem extreme based on the information provided. It screams of a community whose only interaction with enlisted sailors is through a CMC.
It reminds me of an anecdote at a fleet command where a skimmer E9 wanted to send an E5 to mast because the E9 thought the E5 was sleeping on watch. E5 was simply slouching in the chair. The flag officer's response was "are you telling me that there are no leadership tools to correct behavior between nothing and mast?"
Personally, I've only seen two people hung out to dry for security violations. One was compliing information and had a clear intent to sell to a malign actor. The other was an add-on charge to infidelity with another sailor's wife. Every other instance was dealt in a manner similar to
@wink's anecdote - some kind of stern talking to that had no career repercussions or reduction in rank.
Perhaps that's a bad look for the profession. But I distinctly remember a now retired O-6 who flew F-14s early in my career advising me to always separate errors of omission from errors of commission.
Perhaps I'm a hugger.... but I'll exhaust a half-dozen different institutional culture explanations for why a sailor spilled classified information before I conclude that it's a malign actor who volunteered for military service solely to harm the security of the United States of America.
