Re: The BBC used to be more independent.
"Not necessarily. It is equally reasonable to assert that the bias at the BBC is the same as the bias at Ofcom, so Ofcom's people don't "see" the BBC bias (and therefore the complaint is incorrect)."
So what you seem to be saying is that even though you don't know what proportion of those 1,868 complaints were about left-wing political bias and which were right-wing...the BBC is still biased. And because Ofcom has not upheld any of them, then Ofcom has the same Bias as the BBC.
You do realise how absurd that sounds? No, it is not reasonable to assert that Ofcom is biased in the BBC's favour...when you have no evidence of what that bias is.
