A group in the African nation of Cameroon has declared Tuesday “Gay Hate Day” in Cameroon.

The group called Rassemblement de la Jeunesse Camerounaise association (Cameroonian Youth Rally, or RJC) is organizing the event, which is billed as the nation's first annual “celebration” against homosexuality.

Simon-Victor Tonye Bakot, the bishop of the Roman Catholic Archdiocese of Yaounde, called homosexuality “shameful” and “an affront to the family, enemy of women and creation” ahead of the planned events.

Global gay rights group AllOut.org called on Cameroonian President Paul Biya to speak out against the movement and decriminalize gay relationships.

“These anti-gay proponents say they are protecting our 'traditional values.' But we want to tell them that hate and homophobia are not African values,” Alice N'Kom, a Cameroonian attorney, is quoted as saying in a statement released by AllOut.org. “We are bringing together people from across the continent to tell our country that pro-equality voices in Africa are strong.”

“This anti-gay movement is misinforming Cameroonians. A poster announcing the 'Gay Hate Day' claims that hemorrhoids, incontinence and various infections are consequences of homosexuality,” said Yves Yomb, director of gay rights group Alternative-Cameroun. “Decriminalizing homosexuality is a fundamental step in responding to the misinformation, hate, and violence.”

AllOut.org also called on officials to release Roger Jean Claude Mbede, who is serving three years in prison for the crime of sending a text message to another man, which violated the nation's laws against “homosexual behavior.”

“This is the right moment for us to call on President Biya to stand up for equality, discharge Roger, and revoke anti-gay laws in Cameroon,” said N'Kom.
