Surrounded by the skyscrapers that tower over Times Square, a new billboard went up this week that in large black letters reads: “NO GAYS ALLOWED.” Just below, a smaller message states: “STOP Alliance Defending Freedom. Learn more at NoGays.org.” The billboard is part of a new campaign that aims to draw attention to the conservative Christian legal group Alliance Defending Freedom, or ADF, which has been labeled an anti-LGBTQ “hate group” by the Southern Poverty Law Center, a designation the group disputes. Since its founding nearly 25 years ago, ADF has been linked to efforts seeking to criminalize homosexuality, restrict transgender people’s access to sex-segregated facilities and permit businesses to deny service to LGBTQ people.
