This has nothing to do with equality for women. If it were, there would be one standard for military service and any woman capable of meeting that standard would not only be allowed to serve -- they would also be eligible for the draft and duty-bound to fight if called, as it has always been for men.
BO's goal is simply to destroy the "colonialists". Everything he does is understandable if you first understand that motivation.
Staffing our military with women who are unfit to fight is just part of the strategy.
But look on the bright side -- at least it will make the Federal forces easy to beat when the Union comes unglued.
