Another thing where you jump to the conclusion where "problem exists, ipso facto it must be oppression" - except this time its sexism by men.
One of the things I've always thought was silly about the Navy is the inability for such a large organization to guarantee people a long period of time (like, 7-10 years) at a single duty station, rotating from sea to shore at a single location. The amount of money that it costs to move servicemembers around every 3-5 years is staggering, it makes home ownership for career sailors and officers (a big component of most people's wealth) very difficult, and destroys many opportunities for spouses to have careers. With children, another layer is added with regards to consistent education, child care, and friendships.
Women are less likely to put up with it all because they have a higher priority on work / family balance, but that does not mean that the military is sexist. It does mean that they are highlighting long standing issues that have affected servicemembers of all races and genders.
