It's the whole reason a tv licence fee is justified. Impartial news available for everyone as well as educational services. The fact that people see this as a less important and more minor part of the BBC shows how bloated the organisation is.
If anything that's where all the money should be going. Scrap anything else which is covered by commercial channels. Otherwise you are just forcing people to pay for stuff that isn't of national or public importance when they probably don't even watch it.
It would be like if taxes started paying for elective surgery on the NHS or taxes were used to pay for school holidays abroad. These are things that should be paid for by individuals that want it, not subsidised by forcing everyone to collectively pay for it, regardless of whether they wanted it.
The news? local radio? documentaries? children's tv? All makes sense as they serve a genuine public service.

There is plenty of bandwidth available. Get rid of BBC Three HD. Get rid of BBC Four and move the content onto the main channels.
