George Clooney Slams Prop 8

George Clooney has spoken out to E!'s Ted Casablancas about the passage of Proposition 8, banning gay marriage in California:

"At some point in our lifetime, gay marriage won't be an issue, and everyone who stood against this civil right will look as outdated as George Wallace standing on the school steps keeping James Hood from entering the University of Alabama because he was black."

Clooney joins a growing list of stars speaking out including Melissa Etheridge, Harvey Fierstein, Ellen Degeneres and more. Drew Barrymore and James Franco also joined a crowd rallying against its passage.
