Ed Asner is television, stage, and voice actor of some fame, and a former president of the Screen Actors Guild. He has been engaged in various work that I suppose many readers will be sympathetic to, and seems in most respects to be a good guy.
However, he is also a loon. Most significantly, Ed Asner is a 9/11 truther and one of the signatories to the organization 9/11 Truth’s 2004 statement calling for a new investigation into the September 11 attacks, a support he has later repeated. He also narrated the documentary film The Oil Factor: Behind the War on Terror. And as spokesman for 2004 Racism Watch, he wrote an open letter to “peace and justice leaders” encouraging them to demand “full 9-11 truth” through the organization 9-11 Visibility Project. Of course, Asner is not the only celebrity truther, and it there are apparently plans for him to appear in a movie September Morn with other truthers such as Martin Sheen and Woody Harrelson. And no, Asner isn’t one of those who “have a lot of questions;” Ed Asner is a “controlled demolition” promoter. It doesn’t matter what science or evidence says, since those scientists and evidentists are probably part of the conspiracy anyways.
Diagnosis: Doddering, confused fool. Probably not particularly harmful on his own, but he sure does his best to lend credibility to the batshit crazy.
