From a recent article in W Magazine (linked by a posting on PageOneQ)...
In addition to his passionate advocacy for affordable housing--his Make it Right Foundation in New Orleans is building homes for residents displaced by Hurrican Kartrina, and the program may expand to low-income neighborhoods nationwide--Pitt also contributed $100,000 last year to California's "No on Prop 8" campaign, which sough unsuccessfully to block a ballot proposition banning gay marriage. A de facto spokesman for the cause, he has said the he and Jolie will not wed until marriage rights are available to all.
"People who are against gay marriage do not understand the very freedoms that they themselves are enjoying," he argues. "What if someone said, 'Sorry, no Christianity here? No Judaism. Certainly no Mormons.' No one would stand for that, and I wouldn't allow anyone to say that either. I'd fight them in the same way."
Awww... Love you, Braddy-kins. I'll gay marry you!!!
