I've stated this before, but I am going to state it again since it is a hot topic as of late. "Don't Ask, Don't Tell" should be lifted as an actual policy in the military. Admission of your sexual orientation should not be grounds for dismissal from the armed force. We are a free nation, and we should extend those freedoms to those who are willing to protect it...all of them.
I think the effectiveness of a soldier should be determined by their ability to carry out their duties and work cohesively with their brothers/sisters-in-arms. I think everybody can agree with that.
I've talked to all of my friends in the military (and I have quite a few of them), and all of them don't see the problem in repealing DADT, even though a few have their own discomforts with gays due to personal beliefs. They believe that as long as that soldier can hold up their end of the bargain, they are fine with them serving.
