Perhaps "religions" ought to be allowed to advertise; in cinemas, etc.
Claims they make could then be open to scrutiny by The Advertising Standards People.
This would be really interesting ie
Hopey pays for an ad which says faith can cure illnesses, praise the lord and be cured.
ASA declares the ad untruthful and bans it.
Oh what fun
That could be interesting, john. After all, one reason why medical journals are not keen to run articles about faith-healings is that the concept runs counter to the narrative that such journals want to put over - that medical science can, or at least will be able to cure all our ills.
Let's envisage such an ad. Scene 1 introduces a person who has been told that there is no medical cure for their condition and they have only weeks to live and shows an X-ray of the tumour or whatever that is threatening to kill them.
Scene 2, the same person several months or years later talking about how, following prayer, their survival expectancy has increased dramatically and/or their symptoms (eg tumour or whatever) has disappeared completely, again showing an x-ray of the same part of the body.
I realise that some, as some here do, will claim that prayer had nothing to do with the healing, choosing instead to wheel out that famous scientific treatment - spontaneous healing. I'm not convinced that trying to replace 'unscientific claims' by equally 'unscientific claims' really works!!
