Some naively assume that by abolishing the "don't ask, don't tell" policy, they'll end discrimination against gays in the military. The practical truth is that under certain conditions, particularly in combat, open homosexuality can create discomfort and threaten unit cohesiveness.
The existence of openly homosexual service members can lead to apprehension and resentment in units, and ultimately threaten military readiness and morale. The problems would start far before combat (which hopefully there is none or an end).
Unfortunately, some conditions require commanders to use their own discretion in deciding whom to remove. Congress should not interfere with that by injecting the politics of gay rights into the military.
Does everyone here also feel females should be in the SEALs, Rangers, Forced Recon, etc.
