What if they didn't do anything to debunk anything? What if it isn't classified and they just said it was so they don't have to answer? What are they an expert of and is that a reason to not challenge them? Celebrity? So what?

fixing the world, etc. Why? If their movie or show is
good. That is only where they matter...
