Penn: It's important to note that if you're pro-socialism, or anti-globalism, or anti-corporation, those are all fine, debatable ideas. But couching them in environmentalism is bullsh**! Just say what you mean. Don't say, "Corporations are bad because the water is worse today"...because the water isn't worse today. We're not gonna say there are no good arguments for socialism...but the environment ain't one of them.
