Brad Pitt's brother, Doug Pitt, has suggested he disagrees with his mother's anti-gay views but supports her right to have them.

Last week, Jane Pitt made headlines with an op-ed critical of President Barack Obama for supporting marriage equality.

“I think any Christian should spend much time in prayer before refusing to vote for a family man with high morals, business experience, who is against abortion, and shares Christian conviction concerning homosexuality just because he is a Mormon,” Jane Pitt wrote, referring to presumed GOP presidential candidate Mitt Romney.

“Any Christian who does not vote or writes in a name is casting a vote for Romney's opponent, Barack Hussein Obama – a man who sat in Jeremiah Wright's church for years, did not hold a public ceremony to mark the National Day of Prayer, and is a liberal who supports the killing of unborn babies and same-sex marriage.”

Brad Pitt is a strong advocate for gay rights and in particular marriage.

In an appearance on Today, Doug Pitt suggested disagreements are healthy.

“Moms and dads and kids agree to disagree all over the world, so why would our family be any different," Pitt said. "There can be healthy discussion when people disagree with you and I think there should be. The bad thing is when it turns to venom and negativity, and we don't have that in our family. It's open discussion, we can learn from each other. If anything, it solidifies your point or maybe you learn something,” he said.
