So you want a state funded entity that purposely antagonizes a political party that private companies are also forced to compete with for market share? Hmmmm....some of you people are interesting. And by that I mean scary.
Not only that but you want to give them more money and power from public coffers as long as they do more to eliminate political opponents you don’t agree with. Damn damn damn.
Two fundamental flaws with your post.
1. It's not state funded but financed by individuals/households through the licence fee. This is supplemented by income from the broadcaster's commercial arms (eg. the global news service)
2. It doesn't purposefully antagonise any political party.
