In college, I took a course on military sociology from the man who created the DADT policy. When I took the class, three or four years ago, he felt that repeal was overdue. It's good that it happened, and even better that it happened by legislative repeal rather than by court ruling.

Arguments that this will result in increased interpersonal drama in the military exaggerate this supposed problem to such a degree that I have trouble believing they're sincere, even if they were enough to justify DADT in the first place. Gays probably constitute no more than 10% of the U.S. population, and a substantially smaller percentage of people who actually want to join the military.
