I'm not saying that they can't know anything about the subjects that they're advocating, just that many people will believe practically anything a celebrity says on any topic and accept it as gospel truth, regardless of whether or not what they're saying is actually correct. For example, if I told you that stem cell research was morally wrong, you'd probably ignore me and form your own opinion on the subject, as you should. However, if Lady Gaga said that stem cell research was morally wrong, thousands of people would then base their opinion on the topic around what she said, simply because she's a celebrity.
Ah yes, idol worship is the worst
