The Spectator in the UK has organised a screening of the documentary House of Numbers. This documentary "challenges many established perceptions of the Aids epidemic and is sure to generate much debate". Part of the synopsis for the documentary says:

The HIV/AIDS story is being rewritten, and this is the first film to present the uncensored POVs of virtually all the major players -- in their own settings, in their own words. It rocks the foundation upon which all conventional wisdom regarding HIV/AIDS is based.

When it was shown at the London Raindance film festival after they said that they found no inaccuracies. Bad Science says:

This is pretty good for a film which suggests that HIV doesn’t cause Aids, but antiretroviral drugs do, or poverty, or drug use, but HIV probably doesn’t exist, diagnostic tools don’t work, and Aids is simply a spurious basket diagnosis invented to sell antiretroviral medication for a wide range of unrelated problems, and the treatments don’t work either.

One of the limits of free speech is that shouting fire in a cinema when there is no fire is accepted as being wrong.

Is it right that those who deny something like the HIV/AIDS link can have their views aired? Or should we restrict their free speech when lives are at stake?
