Exactly. People vastly misunderstand Citizens United.
Fox News is Rupert Murdoch buying airtime in bulk for his political speech. Unless you propose to shut it down along with every other privately owned media company, money is speech.
Put another way, the CU decision argued that individuals do not give up their right to free expressions just because they decided to pool their money in a particular way.
If money is like cooties, in that it ruins everything it touches, no matter what actual role it plays in the situation, then everything in this world is screwed up forever. But, that's not the case. The real problem with money in politics is the corruption of political, regulatory, administrative, and legislative decisions. When you fixate on stupid shit like some movie some dudes made, that idiocy is quite useful for those who benefit by that corruption.
