Tony Perkins, president of the Christian conservative Family Research Council (FRC), has called Apple CEO Tim Cook's sexuality “irrelevant” as he threatens to boycott Apple.

Last week, Cook acknowledged that he's gay, making him the first openly gay CEO of a Fortune 500 company.

“This may surprise liberals,” said Perkins, an ardent opponent of LGBT rights, “but as far as I'm concerned, Cook's sexuality is irrelevant.”

“It only becomes an issue when homosexuals make it one – and use their businesses as a platform for radical activism.”

Perkins added that his group wants companies not to get involved in “cultural battles.”

“All too often, we get angry at the culture but don't do anything about it,” he said. “Being conscious of where your dollars are going is a small thing that can have a big impact. Regardless of political correctness, money talks. And believe me, corporate America is listening.”

Perkins linked his press release to the website of Faith Driven Consumer, which describes itself as “Christians who choose to live out our faith in every arena of life – including the marketplace.”
