Conservatives are crying foul over a Pepsi television ad they say “promotes the gay lifestyle.”

The ad, which is currently being broadcast in the United Kingdom, shows a young man hitting on another man after passing over several attractive women.

The Christian group American Family Association (AFA) says the ad “promotes the gay lifestyle.”

The ad is just another item in the group's laundry list of complaints against PepsiCo, the company behind Pepsi. In fact, the AFA began a boycott against PepsiCo products, which include Frito-Lays chips and Gatorade sport drinks, two weeks ago.

That boycott was promoted by the drink giant's contributions to the Human Rights Campaign (HRC), the nations largest gay rights advocate, and Parents, Families and Friends of Lesbians and Gays (PFLAG), a support group for parents with gay and lesbian children.

According to an AFA action alert, PepsiCo contributed $500,000 to each organization. The money was used for a national workplace diversity program.

AFA President Donald Wildmon called PepsiCo's response to his objections “condescending.”

“On November 15, AFA received a condescending letter (dated Nov. 7) from Paul Boykas, director of public policy, in which he refused to address Pepsi's support of the homosexual agenda,” the action alert says.

Boykas' laconic response to Wildmon was indeed unapologetic: “Among the values promoted by the PepsiCo Foundation is ensuring a work environment that is respectful and where associates are valued for their contributions. I hope this helps clarify this grant by the PepsiCo Foundation.”

In its action alert, the AFA noted that HRC supported defeat of Proposition 8 – the California ballot initiative that stripped away the right to marry from gays and lesbians in the state – with a $2.3 million donation and called the workplace diversity training a forced acceptance of gays and lesbians.

“Pepsi forces all employees to attend sexual orientation and gender identity diversity training where they are taught to accept homosexuality.”

Last month, an action alert decried ads published in the gay media by Campbell Soup Company, calling them an endorsement of gay families and the “homosexual agenda.” But the iconic American brand said it would not retract from its first foray into the gay and lesbian market.

And last May, the association launched a full boycott against McDonald's for its support of the gay and lesbian community. Among its objections was the burger giant's involvement in the National Gay and Lesbian Chamber of Commerce (NGLCC).

The AFA's position on all three of these companies – and others, including Hallmark and Ford – is that their money helps further a so-called gay agenda.

But increasingly the companies are ignoring such biased protests. For instance, Campbell's executives made it clear that they consider gays and lesbians a positive demographic.

“Our position on this is pretty straightforward,” Campbell's rep Anthony Sanzio told AdAge. “Inclusion and diversity play an important role in our business, and that fact is reflected in our marketing plan. For more than a century, people from all walks of life have enjoyed Campbell's products, and we will continue to try to communicate in ways that are meaningful and relevant to them.”

The AFA, founded in 1977 by Rev. Donald Wildmon, has a long history of objecting to equal rights for gays and lesbians. It has lobbied against gay marriage and hate-crime legislation that would benefit gays.
