I was watching the whole FIFA bribery thing, with some detachment because I am not a sports fan, but with fascination for the way powerful people can stand up in public and insist that wrong is right. Last night Sepp Blatter, who has refused to answer seemingly valid questions about his own alleged bribery, told the gathered FIFA members that "I thought we were living in world of fair play and respect and discipline, but I see this is no longer the case."
I lost a job several years ago because of the behaviour of a dishonest and bullying boss, and very similar phrases were used to describe me by the company, which took his side - I had been "disloyal", "not a team player", "did not walk the walk", etc., rather than taking issue with the various activities the boss was involved in. (He was quietly sidelined and placed under supervision, after they got rid of me, although never disciplined).
Some people described this behaviour, where a figure of authority says something that is unsupported (or blatantly false) and insists that everyone accept it because of who says it, as "management by diktat", "authoritarianism", "boorishness" or "argument by authority". I never found a really good, punchy, single word description for an authority who is wrong - do you have any suggestion?
