Chip and Joanna Gaines' series Fixer Upper is one of the most popular shows on HGTV. The couple has recently graced the cover of People magazine; their book, The Magnolia Story, has been on the New York Times' best-seller list for five weeks; and they were the subject of a long profile in Texas Monthly that credited them with revitalizing the city of Waco, Texas, where the show is set and where their businesses are located. The couple are riding a wave of success, largely due to their charm and appeal. Joanna's design aesthetic — large kitchen islands, open-concept floor plans, and shiplap — is one of the show's stars; Chip's goofiness — his willingness to call himself fat, his sadness and terror when he has to deliver bad news to a client during construction, and his buoyant attitude — is the other.

They have built a small empire, and they are not done yet. They have a huge retail space in Waco, as well as a new magazine, the Magnolia Journal; they have a real estate company; Joanna has a paint line and a home decor line. Season 4 of Fixer Upper begins Nov. 29.

They are also, as they detail in The Magnolia Story, devout Christians — Joanna has spoken of and written about her conversations with God. (God told her both to close her store to spend time with her children, and then to reopen it a few years later.) Their church, Antioch Community Church, is a nondenominational, evangelical, mission-based megachurch. And their pastor, Jimmy Seibert, who described the Gaineses as "dear friends" in a recent video, takes a hard line against same-sex marriage and promotes converting LGBT people into being straight.

So are the Gaineses against same-sex marriage? And would they ever feature a same-sex couple on the show, as have HGTV's House Hunters and Property Brothers? Emails to Brock Murphy, the public relations director at their company, Magnolia, were not returned. HGTV's PR department did not respond to initial emails and calls. Two days after this story was published, they released the following statement: "We don’t discriminate against members of the LGBT community in any of our shows. HGTV is proud to have a crystal clear, consistent record of including people from all walks of life in its series."

Fixer Upper has fans of all stripes: Christians, feminists, and LGBT viewers have all found something to love in the Gaineses. So in the absence of a response from them or their representatives, it's worth looking at the severe, unmoving position Seibert and Antioch take on same-sex marriage.
