From coast to coast, celebrities - gay and straight - are expressing their outrage regarding California's recent move to ban gay marriage. Rocker Melissa Etheridge posted an entry on TheDailyBeast.com expressing her disdain for the decision, saying it made her feel she was "not a full citizen." New Yorker Rosie O'Donnell blogged about the issue on her Web site, saying, "I AM AGAINST PROP 8. DUH." And DJ Samantha Ronson also blogged about the ban on her MySpace page, saying the situation is "really sad to me." Singer Christina Aguilera weighed in, calling Proposition 8 "discrimination" in a Thursday interview with MTV News. "I don't understand how people can be so closed-minded and so judgmental. We chose an African-American president who means so much in a time in history of great change and open-mindedness. Why is this any different? It just doesn't make sense to me." Since Proposition 8 was passed, there have been many protests staged throughout the state, with many notable celebrities in attendance. Wanda Sykes, Rose McGowan and Lance Bass attended a Wednesday protest criticizing the gay marriage ban. Though not in attendance at a rally at a Mormon temple a day later, James Cromwell, Patricia Clarkson, Anjelica Huston and Sean Penn (who stars in the upcoming Harvey Milk biopic, Milk said they supported the protesters while walking the red carpet at the BAFTA L.A. Brittania Awards in Los Angeles. "I think it might be an idea to go out and join them shortly," Penn told The Associated Press. "It was a shameful decision that was made." On her daytime talk show, newlywed Ellen DeGeneres told her audience, "So there was a demonstration here on Wednesday night, and just before I walked out here, I was watching the news and there is a huge, huge, peaceful demonstration going on in the streets, and I say, good for you, and I support you, and if I weren't here, I'd be out there with you."
