Uh, because, like the rest of them (Oprah, Clooney, et al) they are rich and famous and know better than you? What part of famous do you not understand? sarc/off
Some people who are famous, think that means they are smart. Does not work that way. A friend asked on FB if we listened to what others say.. I sad, nope, I was taught to think for myself. That is why I research politicians and other things I read about. Posters on a sports site accuse conservatives on the site of listening to Rush or watchng Fox. I do neither. I read, read and then read some more to make a decision. I am funny that way.
