We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
We cannot keep enemy prisoners in Guantanamo Bay, we are told, because it is a recruiting tool for jihadists. But the repeal of DADT, which will be far and away a greater tool for recruiting jihadists, is a must-do.
I don't fear gays in the military; I served with a number of gays whose soldierly ability ran the gamut.
What I do fear is that the military will be made to accommodate the stereotypical gay lifestyle. There are certain stereotypically manly behaviors that a soldier, particularly in combat, must display. Soldiers who create drama, who let their emotion get the better of them, or who engage in any sort of attention-getting disruptive behavior degrade unit effectiveness. Doesn't mean you can't mourn a fallen comrade; it does mean there's no place for undiscipline and letting your emotions get the better of you under pressure.
Most of the gays I served with were just fine as soldiers, no problems. More than a couple of them, however, were flamboyant drama queens who were so damned disruptive that they got thrown on, not on homosexuality grounds but for being disruptive, which in turn violated sections of the UCMJ other than the prohibition on sodomy. I fear that it is a short step from allowing open & unapologetic service by gays, to forcing commanders to tolerate the hysterical and overly emotional antics that some gays like to engage in. Insofar as gay troops are utterly professional, it shouldn't cause much of a problem; the minute the straight troops start having doubts about the emotional stability and integrity of a gay troop, I suspect it will go badly all around.
To be clear: I do not think that allowing gays to serve in the military will cause the problem; I think that the use of gays as a beachhead for injecting leftist interest group politics into the military will cause enormous problems, and I suspect that is the goal of a lot of the activists involved.
and @ Alan - that's a fine opinion you have there and intuitively correct, but in practice it doesn't work out that way. If you don't have the right aptitude test scores, psych eval, physical fitness, height/weight, ability to understand & follow orders, and ability to make it through training without washing out / getting injured, and the right mental and physical makeup to deal with day-to-day demands of service, then you aren't allowed to serve in the military. It is indeed a privilege, not a right, and people are excluded for much more trivial reasons than the one we're discussing.
