Here is a comment from Huffpo user Abbybwood about 9/11 censorship at The Huffington Post and other sites.
I have been actively involved in politics for over 30 years. Since 9/11 I have been very interested in the investigation that, I feel, did not take place. As a result I have read many books, watched scores of videos and read tons online.
Naturally, from time to time I have attempted to share information regarding 9/11 by posting links and comments at The Huffington Post. Anything I have ever posted regarding 9/11 has been deleted, so eventually I gave up trying. Huffington has a clear rule: "No mention of any conspiracy theories". They even took down an article about 9/11 by former Minnesota Governor Jesse Ventura.
Huffington Post is not the only site that censors comments on 9/11 particularly comments that doubt the "official" story and that suggest problems/questions regarding the 9/11 commission report. CommonDreams has zero tolerance for mentioning 9/11 as does CrooksandLiars. InformationClearingHouse is very tolerant. Salon seems to allow anything as well. About two days ago, ICH had a thread featuring a recent speech by Dr. David Ray Griffin in Chicago regarding 9/11 and the war in Afghanistan. I watched about 7 YouTube links on it, then proceeded to read the comments.
Someone made a comment about Mossad having an involvement with 9/11, then another person asked for links. So I put a series of links and a few comments and went off to another site.
My post is still there and people seemed to appreciate the links. Had I put that post up at Huffington, C&L or at CommonDreams it would have been deleted for sure.
I actually made a comment about Christopher Bollyn's site at The Washington Post online today and I don't think it was removed. (His website is frequently shut down).
Anyhow, I just wanted to tell you of my frustration with not being able to dialogue with my fellow Americans about the worst tragedy in modern American history. There is lots of new information that should be shared about 9/11.
