Alec Baldwin Slams Brother's Anti-Gay Marriage Comments

Alec Baldwin has slammed his own brother in a letter to a popular U.S. gay publication.

The Cooler star took offence to comments born-again Christian Stephen Baldwin made about same-sex marriage on Howard Stern's radio show.

He told the U.S. shock jock: “I don't believe that gay marriage is in line with God's word, which is found in the Bible... and the Bible says that gay marriage is not acceptable."

Alec has now made it clear that he doesn't share his sibling's condemnation of homosexual marriage.

In a letter to gay magazine The Advocate, he writes, "People like that...they want to ban gay marriage because those people are incapable of having a biological family - that's their only argument.

"You can ban gay marriage, but if you're going to make it fair, then you have to ban marriage for everybody else who won't produce children. But they just single out groups of people that they hate."
