A Colorado man has filed a discrimination complaint against a baker over her refusal to sell him a cake with an anti-gay message.

Fox31 Denver identified the man as Bill Jack, a Christian educator who lives in Castle Rock.

Jack alleges that Marjorie Silva, owner of Denver's Azucar Bakery, discriminated against his religious beliefs when she refused to sell him the cake.

According to Silva, she agreed to sell a Bible-shaped cake to a man last year, but backed out when he asked for the cake to include hateful words about gays and an X over two grooms holding hands.

Silva said that the customer would not agree to her suggestion that he write the message on the cake himself.

“It's just horrible,” she said. “It doesn't matter if, you know, if you're Catholic, or Jewish, or Christian, if I'm gay or not gay or whatever,” the 40-year-old Silva said. “We should all be loving each other. I mean there's no reason to discriminate.”

Jack filed his confidential complaint with Colorado's Civil Rights Division.

“I believe I was discriminated against by the bakery based on my creed,” Jack said in a statement supplied to Fox31 Denver. “As a result, I filed a compliant with the Colorado Civil Rights division. Out of respect for the process, I will wait for the director to release his findings before making further comments.”

Mark Silverstein, legal director of the Colorado chapter of the American Civil Liberties Union (ACLU), rejected claims that Silva had violated the state's public accommodation law.

“There's no law that says that a cake-maker has to write obscenities in the cake just because the customer wants it,” he said.

Silva added she “should be the one putting the complaint against him, because he has a very discriminating message.”

This is the second high-profile discrimination case in the Denver area involving bakers. Jack Phillips, owner of Masterpiece Cakeshop in Lakewood, refused to bake a wedding cake for a gay couple claiming that it would violate his religious beliefs. He is currently fighting a legal order requiring him to serve all customers regardless of sexual orientation.
