I tried to summarize what you said. You repeat during 20 lines that it's gonna be bad but don't explain why. The two reasons you give are that it will affect morale and discipline/order.
I'm just trying to understand why it can affect morale and discipline. Is that too complex?
For you, the concept is too complex.
I'll try to break it down, but I'm not getting my hopes up that you'll take this seriously.
You have a group of young men, in an institution that is to say the least, built around trust, honor, and bravery. That's part of being a soldier, sailor airman or marine. The more ground combat oriented the particualr job is, say an army platoon close combat infantry unit, or a marine expiditinary unit... the more the emphasis is on being a "man". Now, right or wrong, good or bad, part of being a warrior is being big, tough, strong and getting freaky with the ladies.
With me so far?
Now introduce an openly gay male into that enviroment.
How well will those manly men respond to a "fairy" in their midst? I can tell you from experience, when someone is found to be gay, things get ugly for that person. No one respects them and and they get drummed out.
But what if they can't be drummed out... what if they are in charge of that platoon? Or that unit? and this person, who NEEDS his people to respect him to carry out the mission... has to overcome that built in prejudice to carry out the mission.
Will it happen? Slowly, over time eventually the idea that your squad leader likes taking it doggie style won't be a big deal, but for the unforeseeable future IT WILL be an issue. That get's people KILLED in the field. Let's say our Gay Squad leader orders his men into the line of fire and some of them balk. Or even ignore the squad leader. That WILL happen. It happened when blacks were intigrated in. Sure, peopel got over that, but it took time, and it was needed.
Neither you, nor any of the other pro-gays serving folks have given a mission oriented positive reason to change the system. It's all about feelings, and whats "fair" vs. what's good for the service. Is the COST of doing this really worth the effort.
I say no, and it's based around saving lives and keeping the military from a needless distraction.
