Family Research Council president Tony Perkins told Washington Watch listeners last Friday that they should oppose gay equality because it will lead to the end of humanity.

Perkins agreed with a caller who said that gay people should be asked how they could exist “if it were not for physical relationship, intimacy between a man and a woman,” a point which followed a long rant about how President Obama is a Muslim under the influence of the Devil.

The FRC head responded that “the human race would be extinct within time if [homosexuality was] normal.”

Perkins has previously warned that government “promotion of same-sex relations” is part of a “push for population control.” Last month, Liberty Counsel head Mat Staver claimed that if gays and lesbians were allowed to legally marry then “everyone” might start “to go towards same-sex marriage” and society would “simply cease to exist.”
