Fred Waldron Phelps Sr. was an American minister and disbarred lawyer who served as the pastor of the Westboro Baptist Church, worked as a civil rights attorney, and ran for statewide election in Kansas. A divisive and controversial figure, he gained national attention for his homophobic views and protests near the funerals of gay people, AIDS victims, military veterans, and disaster victims who he believed were killed as a result of God punishing the U.S. for having "bankrupt values" and tolerating homosexuality. Phelps founded the Westboro Baptist Church, a Topeka, Kansas-based independent Primitive Baptist congregation, in 1955. It has been described by the Southern Poverty Law Center as "arguably the most obnoxious and rabid hate group in America". Its signature slogan, "God Hates Fags", remains the name of the group's principal website.

The Westboro Baptist Church (WBC) is an American, unaffiliated Primitive Baptist church in Topeka, Kansas, that was founded in 1955 by pastor Fred Phelps. It is widely considered a hate group, and is known for its public protests against homosexuals and for its usage of the phrases "God hates fags" and "Thank God for dead soldiers". It also engages in hate speech against atheists, Jews, Muslims, transgender people, and other Christian denominations. The WBC's theology and practices are widely condemned by other Christian churches, including the Baptist World Alliance and the Southern Baptist Convention, and by politicians and public figures, including former U.S. President Barack Obama.
