Fine, but I am not sure how appealing to their better nature and not calling them Nazis does that. Surely to fix the problems in the South and in the media you'd have to actually do something to them to get them to stop?
I've said repeatedly the people who attacked the Capitol are what they are - extremists, terrorists, racists. There's no point in being afraid of using accurate terminology.
When they do horrendous stuff, call it out. That's perfectly fine. That's not what I'm talking about. What I'm talking about is taking the oxygen away from them so their fire doesn't grow in the future. Understanding the underlying cause and effect, not just reacting to the obvious that's happening in the moment.
And yes, you're spot on - Fox News exists because an audience wants it to exist; if you fix society to the point where their narrative is ludicrous to more people, then they no longer have a base to get viewers from.
In the short term, you could have Biden have stricter "OFCOM" style regulation to stop extremism on the airwaves. You can have greater representation of ethnic minorities in southern positions of power over time and so on. But what you can't do is everything and anything to "attack" these things and many others; you have to smart and selective in how you nudge the dial to the left.
