I can appreciate your feelings on the matter, but it's genuinely not that simple. What you're saying is the classic Liberal (in the polisci sense, not the way our news networks use it) argument of "everything comes down to personal responsibility." You need to look at things as a series of systems, not just as a bunch of individuals you can blame. Sometimes, no amount of personal responsibility can fix the system in one fell swoop. The problems that exist, and are baked into politics all over the US, aren't as simple as a single vote, or even a decade of votes, they're problems that have to be solved generationally by fundamentally altering systems.
I absolutely agree with you. AND, there is a "be the change you want to see in the world" part to tall of those systems, the way they are built, run, and managed, that allows the "little man" to have an impact on the system as a whole. One bigoted fuckwit decided she wasn't going to do her sworn duty, and refused to issue a marriage license to a gay couple. That blew up and went viral. She was fired. Big high-powered right-wing lawyers took up her case "for God's sake" and took it all the way to the Supreme Court. (Who refused to hear the case, but that's not germane to my point: She stood her ground, stood for what she saw as "right", and took it all the way. Liberals don't do that. They are too "nice" and try to play nice.) And yes, I agree, those systems need to be fundamentally altered. But that literally cannot happen without making little changes over time. It's tens of thousands of City Council meetings, and small district legislative campaigns, and regulation (or deregulation) that are pushed through, that change the perception of what is possible and "normal", that shift these ossified systems into a new way of operating. Lasting change can only happen over time, with concerted effort. Liberals suck at that. They run off and chase shiny things too often, while shitty religious conservatives quietly beaver away in the background eroding the policies and principles that make our society civil.
I think we’re all, who are in this discussion, fundamentally on the same page. But that’s why you shouldn’t shit all over the “blue South” as you put it. You’d be genuinely surprised by how hard those of us down here work to keep the pendulum from swinging too far right. If there weren’t tens of thousands of people trying to keep the worst of the worst in check, our politicians would be lynching people on street corners by next Tuesday. The South continues to be a battleground, and it’s one where the forces of evil and bigotry have a huge leg up in legacy, institutional systems, and money. But the whole reason that the South doesn’t have town square hangin’s is exactly the kind of small action you’re talking about.
And that, right there, is why I give money to local campaigns in the South. I KNOW there are good people there who are trying to do the right thing and beat back the assholes... but it's tiring work. And not enough people do it. There are plenty of people to turn the tides... they just gotta show up.
