Sexual preference is nobody's business. DADT is a way of allowing homosexuals to join the military without letting others know that they are gay precisely because it is no one's business. As long as they keep it to themselves, the military does not have to make special accommodations for them.
Previously, mental diseases, including homosexuality, were considered reasons to keep people out of the services. Gay activists successfully lobbied (intimidated) the psychiatric profession to remove homosexuality from the list of mental disorders in the 1960s. However, it was still impractical to house practicing homosexuals with straight men, just as it is impractical to house men with women. It is also impractical to house homosexual men with each-other under military circumstances. The Clinton administration came up with an ingenious solution to this conundrum. It was the DADT policy.
If DADT is repealed, the military will be forced to make special accommodations for homosexual men. That is the conundrum. That is also exactly what gay activists want. Gay activists are always seeking special accommodations. Under DADT they were treated equally. If DADT is repealed, they must be treated specially.
If DADT is repealed, gay activists will not be satisfied. They will seek all kinds of anti-bullying rules, sensitivity training, special counselors, rules that allow cross-dressing and using the wrong restrooms just like they do now in public schools.
Gay activists are not interested in equality. DADT provides equality. Repealing DADT requires special treatment and special accommodations for gays. If you don't believe me, just wait and see what happens if DADT is repealed.
If DADT is repealed, gay activists will begin by systematically bringing complaints of bullying and harassment, just like they did in the public schools. This will result in special counselors and special sensitivity training classes. There will be new special rules that affect all soldiers. For example, patting a comrade on his butt will become a crime. Using the word "fag" will be grounds for a dishonorable discharge. This will all be an enormous distraction from the military's prime objective which is winning wars.
If homosexuality is nobodies business, then the repeal of DADT should eliminate homosexual issues from the military. However, this is not what gay activists want. They want to shove homosexual behavior in our faces. They want everyone to know about their sexuality.
I guarantee that if DADT is repealed, homosexual issues will be brought to the forefront in the military, just as it has been in Massachusetts schools where marriage has been redefined to include homosexuals.
The military will be so overwhelmed by accommodating gay activists, that it will distract them from their primary purpose which is winning wars by killing our enemies and destroying things.
