New York City: The American Family Association is taking on the nation's largest fast food chain calling on its members to boycott McDonald's over the company's support for the National Gay and Lesbian Chamber of Commerce.

It is the latest in a series of company boycotts initiated by the conservative Christian group that has, according to financial analysts, had little effect. Previous boycotts have involved Disney, Ford, Proctor and Gamble and Kraft Foods and a threatened boycott of Wal-Mart.

The AFA on its Web Site said that the boycott "is not about hiring homosexuals ... It is not about homosexuals eating at McDonald's ...It is not about how homosexual employees are treated."

Instead, the AFA said: "It is about McDonald's, as a corporation, refusing to remain neutral in the culture wars. McDonald's has chosen not to remain neutral but to give the full weight of their corporation to promoting the homosexual agenda, including homosexual marriage.

McDonald's recently gave a donation to the Chamber and was invited to have a company representative sit on the organization's board.

In a letter to the fast food chain AFA chair Donald Wildmon asked the company to rescind its support for the Chamber and "remain neutral" on LGBT issues.

McDonald's is remaining firm.

"McDonald's is associated with countless local and national affinity groups here in the United States," said McDonald's Global Chief Diversity Officer Pat Harris in a reply to Wildmon.

"We have a well-established and proud heritage of associating with individuals and organizations that share our belief that every person has the right to live and work in their community free of discrimination," Harris said.
