Your description of the world during the 60s and 70s does not match my experience at all. All those sentences I diagrammed in the 70s and 80s, and all the grammar rules I taught as an English teacher throughout the 90s and 2000s directly contradict your story. Corporal punishment and paddling was still a thing in schools and homes well into the 80s.

The civil rights movement, and the other movements for ending discrimination and oppression of women, disabled people, people of color, and LGBT people are why you and I get to enjoy the rights and privileges we do now. These were ethical movements, even though they were, and continue to be, very disruptive to the cultural cohesion of white, Christian America.

Lastly, Hindu and Muslim communities are not generally “stable” any more than any other group. There are over 100 wars in the world occurring right now—a great many of them between Muslim sects or between Hindus and Muslims.

Humans are tribal by nature and we just don’t like those who are “not us”—even more so when under duress, like economic hardship. This is the human condition, and it won’t be fixed by “ethics” or any rational process, because tribalism is not rational, it’s relational.
