That's why I have always avoided celebrity news and political news. I do watch movies and such, and I will pay attention to the policies of the politicians up for vote. But I try to avoid commentators of either.
I learned this lesson as a kid. I loved the band Yes because of their music, then I saw them in a video. The reality that they were not superhuman alien elves with light shining out of their eyes was almost too much to bear. I suddenly realized that we are all just people and every damn one of us sometimes looks goofy and often has some pretty stupid ideas.
I try not to even learn the names of actors, so I won't accidently hear about them saying something stupid and let it ruin their movies. For instance, please never tell me the political views of Amy Acker. I could die happy never knowing her failings. I'm satisfied that she died as "Root" on "Person of Interest".
Actors spend quite a few years learning how to lie convincingly.
We pay actors to watch convincing lies, but at least both parties are aware of expectations.
Some people actually expect politicians to say things that are true (part of the time, at least).
Actually, the same goes for what small children think of their parents (we expect them to know everything, do most things well etc.) but most children eventually learn to accept their flawed humanity.
