Why Did Huffington Post Censor Jesse Ventura's Article on an Event ?

On September 25, 2010, Jesse Ventura, former Navy Seal and detonation specialist discussed his book, American Conspiracies: Lies, Lies, and More Dirty Lies that the Government Tells Us at Baltimore's BookFest. During the session, he claimed the Huffington Post censored his 9/11 article because they "don't do conspiracy theories".

However, Ventura claims his article reported on an "event in San Francisco where 1,000-2,000 architects and engineers signed a petition for a new investigation into 9/11, because these architects and engineers said, unequivocally, the building could not come down the way they told us."

That was not a conspiracy theory...it was an actual event that took place.
