Here's a cartoon from April 2009 by Chan Lowe. Hard to argue with it.
Update: On 24 Sept 2010, US District Judge Ronald Leighton ruled that DADT is unconstitutional and ordered the Air Force to reinstate flight nurse Major Margaret Witt, who actually had not violated DADT (she had not been asked and didn't tell), until a malicious sheriff's deputy entered her home illegally, found evidence of her homosexuality, and reported it to her base commander, who then initiated her discharge from the USAF under the DADT policy. Interestingly, this comes just two weeks after another US District Judge, Virginia Phillipps, also ruled DADT to be unconstitutional. So if these rulings stand, does this mean DADT doesn't have to be repealed by the Congress? I'm not sure of how that works.
