Nope. The dominance of AM radio is driven by boardrooms, not demand. For example: I live in Portland Oregon, one of the most liberal places on the west coast. But what’s on AM radio here? Station after station of extremist right wingers. The content isn’t made here. It’s streamed by the network. There’s no actual connection between the market and the content. The reason it’s on air here is because the parent company dictates it. No other content can gain traction because most of the stations nationally are in the hands of one company. One company with a very specific agenda.
It seems like you have a very strong opinion about AM radio. I am not trying to take that away from you. My point, which is getting lost when you are digging in your heels, is that extremists have always existed. They have always had someone with resources agree with them. But this is the only time in American history that they are able to gain traction. This directly correlates at a global level to what is occurring in other countries. This is not a "their" problem, it is a problem facing all of humanity. This is not an "Oregon" problem or an "AM Radio" problem. This is a "how do we disagree and still communicate instead of devolving into agruments."
While I am sure your area has a specific version of this, it is not area specific, not even country specific. You can see the same issues globally, and not just from more expected countries like the US and UK, but also countries who don't have the same economies/social structures like Egypt, Peru, or even theCzech Republic. It is a global problem. And I am speaking from experience. I have the privilege of traveling all over the world and get to have heart to heart conversations with people from all kinds of different cultures and backgrounds. The theme is there through everything. The internet and its impact on communications (making the world smaller and producing so much more information at a fingertip away) has created some pretty rough seas. Not sure how old you are but thinking about how we understood local, national, and global news in the 80's vs today is so dramatically different. People disagreed back then, people disagree today. Points of view have always been different. But as we lose the healthy exchange of information it creates more polarization and creates an indifferent mass populous that would rather get upset to feel like they can belong to a side than truly exchange information and understand an issue. Bit sized pieces of TikTok, bite sized pieces of climate change, bite sizes pieces of issues with race. Bit sized sensationalized everything. Humanity will find a way through, but I worry about what that journey might look like if we don't come together to figure it out instead of worrying about who is right.
