Before coming out officially, a person believed to be Miller posted about her experience as a closeted lesbian while at West Point on Velvetpark, an online social network for lesbians, under the name "Private Second Class Citizen."
Private Second Class Citizen posted a series of three "lessons" on West Point lesbian culture. In them, she described the secret network of lesbians at the Academy and other classmates' attempts to find out if she was gay. She and her lesbian friends referred to each other as "bros," she wrote. When one of them suspected another classmate was lesbian, she would ask the others, "Yo, is that girl family?" Private Second Class wrote.
In her third "lesson," dated August 5, she revealed that she intended to return to West Point this fall only to come out to her superiors and resign from the Academy. In an earlier post, she wrote, "How is one supposed to wholeheartedly commit to an institution that so blatantly discriminates against them?"
Though she wrote that there was an underground network of lesbians at West Point, it seems few choose Miller's path.
"At this time, we are unaware of any other cadets that have cited the DADT policy as a reason for resignation," Lt. Col. Tribus wrote.
Since Miller resigned before the start of her junior year, she faces no penalty or obligation to the government. Miller has been admitted as a transfer student to Yale University.
"We wish her well at Yale," Lt. Col. Tribus wrote.
Miller wrote that she will continue to fight the policy as a civilian. Miller, who is majoring in sociology, wrote that she has studied the policy and scrutinized it from an academic standpoint. She has written articles and presented her research on the subject at conferences.
"Through my academic endeavors I cannot objectively rationalize the military's policy concerning homosexuality," she wrote. "I intend for my resignation to offer a concrete example of the consequences of a failed law and social policy."
Fulton said neither she nor Knights Out recommend that Cadets resign as Miller did.
"I'm disappointed that she's resigning because I think she's exactly the kind of leader that our soldiers need, but I understand her reasons," Fulton said.
"This is a tragedy for West Point."
If cadets like Miller feel they must resign, Fulton said, she hopes it will energize others to work to change the policy and prevent the military from losing other capable leaders.
Miller said she will rejoin the military if the policy is repealed.
"Service to others remains a core value to me, and I intend to repay my country for all the freedoms I enjoy as a U.S. citizen," Miller wrote. "I have made it a personal responsibility to aid in the improvement of military personnel policy -- as civilian or as soldier -- in order to enhance force readiness and improve national defense capabilities."
