You REALLY have no idea what the military is all about do you? Its not about culture in the same way that you think about everyday society. The Military's job is to kill people and to break things, thats the culture. Whether you are white, black, yellow, red, brown gay, straight or a combination of all of those things it does not matter, Just be really good at Killing and breaking things.
I guess I should have realized that not everyone understands the mission of the military. Hopefully you do now and you appreciate the people who uphold the traditions and culture of the military, regardless of their sexual preference.
