I think that most of the general public are well aware of the BBC's political leanings, and this is reflected in the huge drop in TV licences, year on year, despite a growing population.
I ditched the TV 19 years ago, as I didn't want to subsidise their liberal-left propaganda. Nor did I want to put a penny in their crisp salesman's wallet, or pay for Chris Packham to sneer at me in designer outdoor gear.
The BBC are so arrogant, and detached from reality, that the only way to make them change is to vote with your wallet - and not renew your TV licence.
