Donations from the Jolie-Pitts are pouring this week: first, $2 million to help fight HIV/AIDS and tuberculosis in Ethiopia and now $100,000 to fight Proposition 8, an upcoming California ballot initiative that would ban same-sex marriage in the state.

Trade paper Variety reports that Brad Pitt’s contribution has now become the largest from a high-profile individual in the entertainment business. The hefty sum went to the group Californians Against Eliminating Basic Rights.

The Hollywood superstar accompanied the donation with a heartfelt statement. “Because no one has the right to deny another their life even though they disagree with it, because everyone has the right to live the life they so desire if it doesn’t harm another and because discrimination has no place in America, my vote will be for equality and against Proposition 8,” he said Wednesday.

Other celebrities to have shown solidarity with the cause – also putting their money where their mouths are – include David Geffen, who donated $50,000 and Bryan Lourd, co-chairman of Creative Artists Agency, who contributed $5,000, reports Variety.

Trevor Neilson, Angelina Jolie and Pitt’s political and philanthropic adviser, told the trade paper that Pitt considers this a “human rights issue and an issue of justice.” He told the Associated Press that Pitt was surprised there were not more donations from individuals in the entertainment industry supporting the battle against Proposition 8.

Same-sex marriage is legal in Massachusetts and California but this could change for the latter state should the November ballot initiative be successful and overturn the state Supreme Court decision legalizing same-sex marriage.

Brad Pitt famously told Esquire magazine two years ago, when questioned about his relationship with Angelina Jolie, that they would “consider tying the knot when everyone else in the country who wants to be married is legally able.”
