Between those two points there will be war fighting to do, and having lost, being able to say, "Yeah but we weren't racists or misogynists so we retain the high ground." is going to be a real comfort.The problem with that approach is that you will never reduce the very real problem of racism, sexism, etc in the military while it is excessively dominated by white males.
Once the organisation has rid itself of its racist and sexist, etc culture, then the true meritocracy can be applied.
