Once again all the accounts of what happened with 911 are conspiracy theories, including the officially accepted one.

It makes sense to denounce particular theories as junk, but we shouldn't ever use the term " conspiracy theory" as if it meant the same thing as junk.

Much of the time the offcial theory may well be the closest to the truth. But not always. Often it happens when secret papers are published years later it turns out that in very important aspects the official account was significantly misleading. We should always be open to the possibility that we are being told lies.

For example in England, it is now clear that the official account of the Hillsborough Disaster was a tissue of lies, signed up to by the highest authorities, involving large numbers of police officers knowingly cooperating in backing up the lies.

Misusing the term "conspiracy theory" in this way just makes it too easy for the authorities to avoid dealing seriously with serious misgivings.
