Megan Phelps-Roper is an American political activist who is formerly a member of, and spokesperson for, the Westboro Baptist Church, a Hyper-Calvinist Christian sect, widely regarded as a hate group. Her mother is Shirley Phelps-Roper, and her grandfather is the church's founder, Fred Phelps. She grew up in Topeka, Kansas, in a compound with other members of the church. As a child, she was taught the Westboro Baptist Church doctrine and participated in the church's pickets against homosexuality, the American response to the September 11 terrorist attacks, and the funerals of soldiers who died in the War in Afghanistan and the War in Iraq. In 2009, she became active on Twitter to preach the church's doctrine. Phelps-Roper began to doubt her beliefs when Twitter users pointed out contradictions in the Westboro Baptist Church's doctrine, and when elders changed the church's decision-making process.

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.
