An awful lot of natural behaviour has been suppressed, and not just in West Point.
Virtually every school in the country is adamantly opposed in policy to boys being boys, unless they are homosexuals, which would have been an outlier and not mainstream. Aggression, self control, pecking orders were hammered out in scuffles and conflict, not cause to discard the student (kick them out) unless they showed a pattern of rank oppression, a trait which was discouraged. But then, too, generally male teachers, coaches, and administrators were not just cowed candy-asses hiding behind a policy manual, but often, fully masculine role models for young men.
