An employee fired over an anti-gay posting has sued his employer and Ford, claiming that he was wrongfully terminated.

Thomas Banks of Ypsilanti, Michigan lost his job with Rapid Global Business Solution last year when he criticized Ford's support of the LGBT community. Banks, a contract engineer, had been on assignment at a Ford plant in Dearborn for more than three years.

Banks responded in July, 2014 to an article about Ford's commitment to the LGBT community on the automaker's intranet, according to the Detroit Free Press.

“For this Ford Motor should be thoroughly ashamed,” Banks wrote in the story's comments. “Endorsing and promoting sodomy is of benefit to no one. This topic is disruptive to the workplace and is an assault on Christians and morality, as well as antithetical to our design and our survival. Immoral sexual conduct should not be a topic for an automotive manufacturer to endorse or promote. And yes-this is historic-but not in a good way. Never in the history of mankind has a culture survived that promotes sodomy. Heterosexual behavior creates life – homosexual behavior leads to death.”

In terminating Banks, Ford said that he had violated the company's anti-harassment policy. Rapid Global followed suit.

At the time, Banks, a Christian, said that he had simply expressed his faith.

In his federal lawsuit, Banks accuses his former employers of violating his civil rights.
