Malcom Gregory Scott (born January 26, 1962) also known as Greg Scott, is an American writer, activist, and AIDS survivor. In 1987, the United States Navy (USN) discharged him for homosexuality, after which Scott worked to overturn the Department of Defense (DoD) directive prohibiting the military service of lesbian and gay Americans. Upon his discharge, Scott also learned he had tested positive for the Human Immunodeficiency Virus (HIV), the virus that causes Acquired Immunodefficiency Syndrome (AIDS). He was active in the Washington, D.C., chapters of ACT UP (AIDS Coalition to Unleash Power) and Queer Nation. Scott was an advocate for legal access to medical marijuana, a critic of early HIV prevention education strategies, and a proponent for expanded academic research to support the public policy goals of queer communities. American journalist Michelangelo Signorile once called Scott "the proudest queer in America." Scott worked as a writer for Fox Television's America's Most Wanted, and his writing has appeared in several newspapers and magazines. Scott nearly died of Stage IV AIDS in 1995 and credited marijuana with his survival until effective anti-retroviral therapies became available.
