Irvin credits his father with helping him accept his brother's lifestyle and now says the African-American community should support marriage equality.
"I don't see how any African-American, with any inkling of history, can say that you don't have the right to live your life how you want to live your life," he said, according to the magazine. "No one should be telling you who you should love, no one should be telling you who you should be spending the rest of your life with. When we start talking about equality, and everybody being treated equally, I don't want to know an African-American who will say everybody doesn't deserve equality."
There have been detractors, too. In June, former Super Bowl hero David Tyree said gay marriage "will be the beginning of our country sliding toward, it's a strong word, but anarchy."
But Irvin, who had his share of off-field trouble during his playing days, has no such hang-ups. "If anyone comes out in those top four major sports, I will absolutely support him. ... When a guy steps up and says, 'This is who I am,' I guarantee you I'll give him 100 percent support."
