I think you are fair here, it's not gone unnoticed.
I know I used to be worse as well, but I've spent enough time in both red and blue America over the course of my life to conclude that folks in both groups don't understand each other or their wants/desires well at all. Which is understandable enough, most people are working for a paycheck and are most familiar with what's in front of them in their daily lives. That crosses the political spectrum - people are just trying to get by, and we should better understand that.
What is discouraging is that there is really little appetite to even try to understand how different people live outside of what is familiar in one's day to day life. We just project our own beliefs onto people who live different daily realities and then just stereotype them. And then we act shocked that we are bitterly divided and little trust exists in society.
We'd all do better, not just on this board but in society as a whole, not to just assume the absolute worst in people who don't think or believe as one does. Or live in places that are different than what one is accustomed to. But unfortunately, with our current set up, that seems unlikely to happen any time soon.
