Brian's Auty Beeb is a rare exception - a public service with some presence, but as their own [white male] chairman pointed out last month, it is in danger of being squashed by BSkyB, which is Murdoch or one of the other white blokes' company.
Despite the BBC's excellence, let's check out Brian's contention that it's being used as a tool for the dilution of the power of white men, who have controlled the world for the past twenty centuries:
You keep mentioning "the BBC", although I see you got as far as BBC4 as the main problem.
BBC4 claims a "reach" of 10 million listeners at an average of 12.3 hours per week.
Note that is the BBC's own figures.
I can't find any age demographics for it easily, but I'll guess that it shares with the almost-identical RNZ National program, an older age group listener as its main audience.
Also, the "reach" figure is entirely misleading, because that is everyone who is within listening distance of a BBC4 radio program during the week. How many people actually listen, and care about what is being said on radio in 2010?
Regardless of whether there is a bias on BBC4, I suggest that basing your argument on what happens on talk radio is little better than if I base my argument on talk
back radio, in which case I would present white men as xenophobic racists who are frightened by anyone non-white..
