Not to be difficult, but I don't think most of those are accurate (will get to that in a second). Even if they were, though, the majority of them are not political philosophies, they are social philosophies.

One by one:

1. Nationalism—American nationalism certainly began to be questioned in the 60s in conjunction with the Vietnam War controversy, which rose to a fever pitch by the early 70s, and the rise of the environmental movement in the 70s and the acknowledgment of the US' role in environmental pollution, Watergate, which tremendously undermined citizens' confidence in our government, the push for multiculturalism and "diversity" was huge in the 70s.

I agree that the word "nationalism" hadn't become verboten by then, but the concepts were alive and kicking.

2. Family. The divorce rate more than doubled (actually almost tripled) between 1965 and 1979. "Blended families" and single parents were socially normalized on t.v. The top ten types of families (two parents with one child, two parents with two children, one parent with one child, etc.) accounted for 83% of families in 1970 and 85% of the families in 2014. Again, no one was talking about gay people raising kids in 1975, but that's a popular topic today that happens to affect almost no one. The LGBTQ+ community is still very small, it just gets a wildly disproportionate amount of attention these days.

Roe v Wade happened in 1973.

3. Race relations—I'm not sure what you mean by this. Black colleges that excluded whites were promoted heavily in the 1970s. Remember "A black mind is a terrible thing to waste?" Though they peaked in the late 60s, the Black Panthers didn't disband until 1982; they were active during the entire decade of the 70s. The Nation of Islam was at it's peak in the mid-70s.

4. I'll give you this one.

5. If what we're talking about is eminent domain, that began to be eroded well prior to the 1970s. Berman v Parker, which is what really got the ED ball rolling happened in 1954. And the next huge nail in that coffin happened in 1978—the Penn Central decision.

BTW, Trump planned to use imminent domain to seize land to build his border wall. And that's a good example of what I'm talking about. Trump and Bernie Sanders could have a beer and get a long just fine if they talked about eminent domain and trade tariffs. Nary a cross word between them.

6. Not sure how much the state endorsed religion by the 70s, even if we restrict the definition of religion to the Christian religion. But again, the social cracks in the foundation of traditional religious institutions began before the 1970s. Remember the "Is God Dead" Time magazine cover? That was 1966. I won't dispute that the numbers of the religious have steadily decreased since then, but I do think it's worth noting that it had already started before the 70s.

Productivity and merit—Affirmative action started with Kennedy in 1961 and by the 1970s was being aggressively applied to college admissions. And there were plenty of communists in the 1970s. Remember Patty Hearst? Those "Liberation Armies?"

I don't know, man. I think what's mostly different now is perception. JMO.
