I seriously doubt either side of the Great American Divide has altered the fundamental position of the opposite side, here on jazzfanz. Certainly, I can hear the contempt in your "whatever you like to call yourselves", and it has often been reciprocal of course. Basically, much of the conversation in these many Trump threads has been in the form of people simply talking past each other. I also believe there are very fundamental psychological differences in how liberals and conservatives see and interpret the world. And there are so many ways in which those differences, and our divisions, can be described and examined. For instance, much of our history can be seen as a struggle between the values of urban dwellers vs. the values of rural folks. The stark divisions we see today have been present throughout our history.
I would never presume anything I could or would say, would alter how you feel and think. Of course, if we are to survive, and even once more thrive, beyond our present Great Divide, we will someday have to find a way to recognize some commonality in our all being citizens of this country. We will have to give up trolling and aiming for pounding the other side into submission. Someday.
