Borrowing from a friend's blog, because I just couldn't say it any better.
Political Pistachio: Don't Ask, Don't Tell - Lady Gaga and the Democrats:
"In those rules created by Congress are the limitations regarding who can, and cannot, serve in the armed forces. The determinations are based on what the military, and Congress, believes to be what most benefits the discipline and battle readiness of the military. Limits on height, weight, physical abilities, family status, and a whole host of other things, are all in place to make sure that our fighting men and women are the best of the best. In response, should potential service members that are denied the opportunity to serve for being too tall, or too fat, or unable to pass the fitness tests, or are single parents sue the government because their 'Constitutional Right to serve' was denied? Should married service members who are denied nuclear submarine duty demand that the military not deny them the right to serve aboard a sub?
The answer is obvious. These people are denied for reasons that include what is best for our military. They don't have a right to serve any more than does homosexuals.
What is best for the armed forces is the issue at hand, not what is best for the individual."
Please read the entire post. It's worth your time.
For my part, I applaud those of a patriotic spirit with physical/mental disabilities or chronic illnesses, those who simply don't meet the height or weight requirements and those who may be too individualistic to pass the psych evaluation who don't attempt to put their personal agenda over the lives of their fellow Americans by insisting that they , too should be allowed to serve. They also serve who sit and wait.
