I served for 5 years in the Army as an officer, but I was a ROTC-nazi, not a ringknocker. I knew two basic types of West Pointers:
1: The Super-Lifer who was all-in on the kool-aid and brainwashing. These are the vast majority I knew. Not necessarily autistic, but extremely socially awkward and not very fun or funny. EVERYTHING was dead serious, and the only things they found funny or humorous is the inane processed bullshit on TV that Holla Forumsacks cringe at and even some normies find lame. Didn't seem fully "human" if that makes any sense and the vast majority lacked ANY ability to think critically. While most were reasonable people, I knew a few that were so deep into "the Army" never being wrong that regardless of the morality or constitutionality of an order, they would follow it. They would machine-gun an entire town in front of TV cameras if ordered. They were the minority within the group, but they did exist.
2: The dudes who did it for family reasons and didn't give a fuck. These guys were a definite minority, but I knew one or two. They did their time, got out and did something else. All the others stayed in.
Regarding the first group, Fred Reed wrote a (few) column(s) about service academy types and his hypothesis was that they were emotionally-stunted and repressed, and unable to deal with complex thoughts and emotions. His point was that 18-23 are your prime years to "develop" yourself and cut loose. Nothing really "degenerate" as folks here would think, but those years are when you're out of the house, on your own, and you're supposed to go party, smoke a little weed, bang chicks, do dumb shit, and learn your limits while blowing off steam.
You take kids at that point in their life and then force them to spend the next four years being under the control of someone else who makes most (all) major decisions for them, keep them way too obsessed about how shiny their belt buckle is and how "dress right, DRESS!" their clothes and room is, never really let them blow off steam and act "normal", and never let them develop their own minds and critical-thinking skills.
Turn them loose in a military unit and these are the kind of people that can command Divisions and Carrier Battle Groups, a difficult task and one that not many people can do. They are smart people and can analyze information and can make decisions quickly. But ask them to reflect on the morality or righteousness of what they are doing, or in any other way go against the indoctrination or brainwashing, (basically try and redpill them), and they absolutely cannot handle it. Their brains literally are not wired to process and deal with that shit, and it comes from the roles they chose (or were put into), at those critical developmental times in their lives.
Having known more than a few of them, I think Fred is pretty spot-on.
