How does the political and cultural polarization today compare to that in the 1960s?
I was a teenager in the late 1960s, and I was paying rapt attention to what was going on. So I speak from that perspective.
1. The most bitterly polarizing issue was the Vietnam War. From 1965-1968, the most bitter division among political office-holders was Democrat against Democrat. President Johnson and his supporters defended the war. Senator Fulbright and other leading Democrats in Congress opposed it.
2. When Richard Nixon became President and continued the war, with expanded bombing, the issue became more clearly partisan, with Democrats opposed. But a lot of the public pressure to end the war slowly eased, because Nixon drew down the number of troops, ended the draft, and ultimately signed a peace agreement.
3. Culturally, the hippies were a big phenomenon in the late 1960s. They contrasted with working-class youth, who were known as “greasers” because of the product that young working-class men wore in their short hair. But by the mid-1970s, there was no more divide between hippies and greasers. Guys of every social background had long hair, along with those mutton-chop sideburns and thick mustaches so emblematic of the decade. And the hippies grew up, took showers, and got jobs. So I would say that by about 1975 American culture was more blended than separated. And of course back then everyone saw the same movies, watched the same TV shows, and had the same news sources.
4. Today, I would say that there is nothing as politically divisive as the Vietnam War. There is no enduring political issue per se. Like Seinfeld, politics these days is a show about nothing.
5. Instead, what we see now is plenty of political rage, directed against particular individuals or particular groups. The actual issues that attract attention are relatively minor incidents that get magnified in the media. Gone are the common sources of information, so that many people seem to live in bubbles in which those who disagree appear to be demons.
6. Today, the cultural divide is much starker. Social classes have much less interaction with one another, and this reinforces the tendency to demonize others.
On net, I believe that this is a more dangerous time than the 1960s. I suspect that many people would like to see the divisions healed. But the path that led to healing of the divides of the 1960s is not available today. We will have to find a different path.
