That's even a more difficult problem. Militaries have a horrible history when it comes to "others." My Thai wife's Thai/Lao grandmother taught her that no Thai woman went unraped during the Japanese occupation of Thailand during WW2. Far too many American GIs view "others" as LBFMs. Too many are happy to have sex with child prostitutes, etc. Will an "us", all men are brothers and all women are our sisters ever become a norm? How much of that is due to the dominance hierarchy and how much due to something else? I don't know.
My point as always is that a bottom up cultural change in attitudes is essential. Top down system approaches have a spectacular history of failure because humans don't care about the "system" and always act in defiance of it when it doesn't suit them. How do we bring about a change of heart?
