I'd say it's "unhinged" to call this "unhinged." It's absolutely nothing of significance. I am so sick of the way any display of emotional intensity is characterized as a mental disorder. It shows: 1. a prudish concern for decorum and 2. a lack of compassion for those who actually do suffer from mental illness. I would think liberals would reject both things, but again and again — on the web, at least — I see that they don't.
ADDED: I watched O'Reilly's coverage of the incident (on his Monday show), and in it we see that he pushes the man a couple times. O'Reilly had two friendly female commentators on the show to talk to him about it, and one of them tells him the shoving was wrong. The other accepts it — under the circumstances. It seems to me that both the large man doing the deliberate blocking of the camera's shot and O'Reilly with his pushing were acting out in a rude, macho way, but it wasn't crazy. Both were pursuing their own interests and choosing their techniques. My post isn't about right and wrong, but about sane and crazy. They weren't crazy.
Now, there is a further question about whether these 2 sane men who pursued self-interest had good judgment about what they ought to do. Here, I think, clearly, O'Reilly won. It worked for him within the context of what he does. People working for the campaign should not be displaying hostility to the news media, and they should especially not discriminate against Fox News.
By the way, Barack Obama looks great in the final O'Reilly edit. He sees O'Reilly — when O'Reilly calls out to him from back in the crowd — and comes over and shakes hands, seems relaxed and warm, and agrees to meet with O'Reilly after the primary. He's setting a good example for everyone.
