I hate it. The last 9 years have been hell for me because this asshole won't shut up and the news insists on blasting every stupid thing he says. It doesn't matter if he thinks drinking bleach is a good idea. What matters is the news broadcasts this so people that already know he's an idiot can laugh, and those that don't think 'well if der president says it makes sense it must'. What you get is 1. a decrease in average intelligence, and 2. constant name recognition for a rapist felon with no business acumen who chronically lies and wants to literally destroy democracy.
The problem as I see it is how the news portrays every little thing the left does (or just things that happen on the left's watch) with the exact same sensationalism as every radical thing the right does and says. If anything they tone down what the right does so it doesn't sound extreme.
Like finding the most extreme loud leftist protester to compare to actual elected delegates on the right or militant groups on the right that officials actually back. Meanwhile if the right wipes their ass without making a mess, they are hailed.
The left is judged on their worst and the right is judged onto their best, and the left still usually comes out looking better.
The Fairness Doctrine is a red herring in the conversation either way. Even if it hadn't been rescinded, it would have eventually become irrelevant.
The Fairness Doctrine only ever applied to radio and TV broadcasters, i.e., broadcasters operating using the limited, publicly owned radio spectrum. It was only Constitutionally enforceable because it was intended to ensure equal access to what was essentially a public space.
Cable TV and the Internet turned that completely on its head. Attempting to regulate speech over a privately owned medium is a very, very different legal hill to climb. The most problematic sources of misinformation and bias today tend not to be AM radio but things like NewsMax or Libsoftiktok.
It's a huge problem, but it's not one the Fairness Doctrine would solve.
