I think that once you open the door and allow people in on a certain aspect it's very hard to then control how far that ripple effect is. So I think that the person who is known or famous has the ability to decide what they do or don't want to share.
When you take a stand out of deep conviction people know. They may not even agree but they ask 'Do I want someone who is willing to take a hard stand and someone I can trust to do that when the chips are down?' They want that.
