Lady Gaga was escorted by military men in the MTV VMA 2010 and as she explained, this is part of her advocacy about "don't ask don't tell" policy in the US military. Don't ask don't tell or DADT is a long been controversy in the US military regarding gays joining the arm forces. It is law that prevents openly gays to be in the US military, once proven he/she will be discharge from the service.
Serviceperson's Legal Defense Network (SLDN) reports that even if some service men kept their gender closeted, some members exposed them and violated the policy.
Now Lady Gaga stands to her advocacy and speak out. She mentioned few examples and people behind her supporting. She is calling out people of America to ask their senators to repeal DADT policy and give people regardless of their gender a chance to serve their country.
