I don't see any coming together of "us" and "them".
Liberals, progressive, Democrats - we reason, our minds can be changed with good reasoning and discussion (not slogans). We see the world as one - people of all types of equal value, we work toward all making progress - we delight in diversity. We are open minded, see science for a way to learn about our world, a way to move forward. We have a sense of humor, can laugh at ourselves when we are ludicrous....we understand satire, and irony. We cherish the arts, relish creativity. We work hard to not fall prey to propaganda - we always engage our brain, yet we also have big hearts and sometimes find it tough to put our feelings - our emotions - into words. We tend to be optimists, yet we see what is coming - be it COVID (and how it is being mishandled), Climate Change (to me, this is the BIG ONE). We strive to work for the win/win. We tend to chafe at authority, and authoritarians.
Conservatives see the world not only as us and them, but me and you, and to them, life is win/lose. Those that are beholden to fire and brimstone, preach from the pulpit, my way or the highway are unreachable - they are THE chosen and the rest of us are doomed chumps. All ideas have to benefit corporation, big business. They exhibit cult and herd mentality and whatever appears from the mouths of those on Faux News, or right wing hate radio, becomes embedded as truth. They live in a world of hoaxes. Many are insanely jealous of anyone who is like us - that can laugh, form healthy relationships, and can work through complex issues, rather than just go for the two word meme. Many are just spending their time here on earth as a way station waiting for the big rapture, in which they firmly think that THEY are chosen to move on. Though they benefit from things scientists and creativity make, they can't or don't want to understand it, so are living a life of hypocrisy. Each has a one issue trigger that cements them into this conservative box - be it abortion, religion, guns - but that single issue is the deal breaker. There is no reason beyond it.
How can those two world views ever come together? How can our country move forward when the majority are being held hostage by the minority world view? And I am only referring to the ideological split. Overlay on that the seduction of power and money (which tends to override ideology - the true haves and have nots - another way to slice the pie.
These are the things I ponder as I lie in bed at night....and after my coffee (as in now). Either it was always like this and it takes some experiences and years to see it - or we are in one of those make or break critical places in history.

Then, they lose all interest in further participation.
