There is a false perception, sometimes advanced by those who are very pro-military themselves, that everyone in the military is (or at least should be) more moral, virtuous, etc., than the population at large, embodying the best about us, etc.. That perception is then hijacked by social justice warriors who use it to justify using the military as an engine for social change. After all, the military is more disciplined, can be forced to accept things even if troops don't like it initially, and can be expected to overcome any minor problems because "that's how great our military is."
The truth is, some of the very best actual fighters don't fit that mold. They're not all "boy scouts" of impeccable moral character, nor should we expect, demand, or require that they be. Sometimes, your best ass-kickers aren't people you'd want to marry your sister or daughter. They're rough, crude, and absolutely necessary to maximizing the combat performance of a unit. That's part of the esprit of great combat units -- the rough "soldier's humor", the camaraderie that comes from a somewhat coarse working environment, etc.. Turn our military into nothing more than a sanitized safe space for whatever whiny group is next in line, and you're going to chase off a lot of the folks you'll really need when the fecal matter strikes the rotating blades.
