> This is the culture of the moralist left, of the blue cities, of the Coast, of Progressivism as the only moral ideology
> In the US, at least, if you engage with conservative culture, with Christians, with rural people, with the people who are tired of "cancel culture," you will still find plenty of grace.
As is often the case with generalization born of prejudice, this effort to split good and evil along ideological lines fails to match up with reality. Plenty of Progressives give grace to people around them. Plenty of Christians ostracize and abuse even the people closest to them. The vocal hypocrites on either side loom large for their ideological opponents and the quietly good on either side are easily ignored, except by their ideological peers. This pattern holds in rural towns and huge cities.
The problems of selfishness and hate for others are difficult to solve, and unfortunately even a framework as simple as Christ's demonstrates that. Try not to get too comfortable with the belief that people who see the world differently aren't still trying to navigate it kindly.
