GLAAD stands for 'The Gay and Lesbian Alliance Against Defamation' (Link here). Their whole mission is to protect and and promote the stories and acceptance of members of LGBT communities. GLAAD also reports on any issue relating to LGBT, and is promoted by many known companies and celebrities. Wells Fargo is a big supporter, as well as Anderson Cooper, who recently came out about his sexuality. Ellen Degeneres, Ricky Martin, and Liz Carmouche (UFC fighter) are also among supporters of GLAAD.
