Penn Thinks He Knows

Why is it that famous people like Sean Penn think they have the right to jump into world affairs just because they have made a few movies. (Most of them Shitty) Furthermore what gives them the idea that Americans care about what they are talking about or that they actually have valid points. You don't see me traveling over to Iran or Irag and making believe I know what I am talking about and expecting everyone to listen to what I have to say. I say shut up and stop acting. http://www.editorandpublisher.com/eandp/news/article_display.jsp?vnu_content_id=1000963024
