Brad Pitt has long supported gay marriage but in a recent interview to promote his new movie, Killing Them Softly, he explained why.
“Equality, absolutely, that's what defines us. It's what makes us great."
"If it doesn't sit well with your religion, let your God sort it out in the end, but that's us. We're equal."
Pitt says he understands how important making progress with social issues is, but he takes a different view on legalising marijuana – an issue which has been conflated with legalising same sex marriage in the United States.
"I don't understand what the issues have in common. I do believe that we should be responsible for our own choices in talking about the drug laws, and that the drug war is an ultimate failure and that the billions and billions of dollars that we've committed to it — there's got to be a better way. I don't believe in incarceration over education — don't get me started. But there's real damage to drugs; that is not the same as with gay marriage. Since the last round [of elections], they've been linked in every article. I find that curious."
He said he dreads having a conversation with his children about drugs.
"I think there's an age of understanding and there's a reason why there are no old drug addicts: It either kills you or you get out," he said. "I'm going to leave it at that point right there."
He also declined to name a date for his marriage to partner Angelina Jolie but admitted he is getting pressure from their brood.
"We're getting a lot of pressure from the kids. We didn't realise how much it meant to them and then, in getting engaged, how much it also means to us."
