It’s not like the 1950’s, when Jimmy Stewart, a very prominent Conservative, and Henry Fonda, a leading Liberal, could remain close, personal friends.
It all changed in ‘72 when they adopted Alinsky’s politics of personal destruction IMHO. You can’t even have a rational conversation with these people anymore.
I have been telling people for more than two years that we're headed for civil war. Few believers. I will be vindicated.
The identity politics that has reached the point today of starting sentences with “I identify as” or “my demographics let me give this opinion ...” began around that point as “we’re good, moral, tolerant, rational, educated, you can look down on everyone else as outside of the elite self-appointed tribe”.
It was compounded by liberals importing ethnic minorities intentionally to fracture American society into competing groups and telling the existing groups “You’re under siege, form tight tribes for protection, and follow the people who will protect and lead you - Democrats!”
So now people tend to identify with their demographic tribe tightly, and the merging of ideology (faith/nonfaith) and demographic identity means the tribal forces enforce political conformity - and if you violate the faith/ideology, you’re expelled from the tribe as not really a member or punished as a traitor.
Hence liberals can say conservative women aren’t really women, conservative blacks are traitors to the race.
