I think that is probably true today.
People who have no lives outside of “blogging” or being tied to the digital umbilical cord might think the values are different. MOST people really have better things to do with their lives.
I would suggest that you could start a conversation with anyone and after a while, if you are being really honest, you can agree on 90% of stuff. The things that divide us can be compromised. But no one is willing to give an inch these days.
That was the idea of “statesmen”—like the many folks who worked very hard to avoid a Civil War in the 1820s, 1830s etc.
I have no problem imagining an alternate history with a peaceful parting of the ways—but hindsight is 20/20—cooler heads did not prevail.
