Younger than that. I do remember a little of the crazy talk of the 70s.
Some of the changes set in motion back then had a major effect in the country over the past 30 years, but I don't think you have all the "Summer of Love"/"Days of Rage" madness now that you had back then.
If you want to say the country's more liberal than back then, go ahead. If you want to say it's crazier or more likely to fall into the abyss, I'd argue with that.
Maybe it's a glass half-empty/glass half-full thing. From what I can gather you didn't have teachers talking about multiculturalism or homosexuality in the schools forty years ago, but the fact that kids hear that from teachers may make them less likely to believe it.
Being younger you've had to make do with the media's rendition of the 60s and 70s.
Being someone who lived it I can attest that all that summer of love and yippie and fembot and black panther and stonewall riots vanguard movement stuff was just the periphery that got a lot of media attention.
The average college student even at Madison or New Haven was not a rioting radical.
Back then we had a silent majority that was very socially conservative and supported Vietnam up until Nixon's faux Peace with Dignity crap which they shifted towards.
Socially we were markedly more conservative and freer. Very few gun laws, abortion didn't start off till 1973, little racial preference stuff, no inkling of homo-marriage, none of the intrusive confiscatory laws, no hate crimes laws, almost no intrusion on free speech contrary to the media.
Back then the status quo was a staid establishment that grated against the colorful Age of Aquarius and lots of reasonable folks may have thought that yes ..just like loosening up Jim Crow regs that maybe the culture ought to be a little more live and let live but that is as far as it went in the mainstream on social evolution.
The insane crap we now deal with is what those who resisted all that breakdown warned against and they were right.
