For more than 40 years in journalism and PR I've been struggling to find one. Clearly some are cleaner than others, but none is exempt from ethical issues. It is the degree of damage that needs determining and where the line is drawn between acceptance and rejection.
Most 'ethical' investment funds, for example, usually list tobacco, alcohol and armaments as the key stocks to avoid. If governments followed their lead, smoking and alcohol consumption would be banned immediately. And talking of fascism, perhaps Hitler - who we can agree was not 'ethical' - would have been allowed to rule the world, because the Allies would have had no weapons to prevent the Nazis.
Everyone in PR should support Lord Bell's view on free speech. After all, what's the alternative? Indeed, open debate is the means to help us decide what is 'right' and 'wrong'.
