I'm not so sure about this The 1950's were so intensely socially conservative in so many respects.
I think you are confusing the actual 1950s - a time of rapid social change and cultural vibrancy across the industrialised world West and East - with the strange fantasy 1950s that often pervades American political discourse.
Nietzsche had himself been dead for half a century by that point, dear.
Academia wishes it was that influential. Actually academia wishes it was about 5% as influential...
1. It is true that there were many rapid changes in the 1950's, but at the time, church attendance was at record highs, a majority of people thought religion's influence in public life was increasing, the average age of marriage was dropping, etc. etc. etc.
2. My point was referring to Newsweek's article in 1966 about "The Death of God." It is true that intellectuals had always been far more secular than the public at large, but thankfully they tended not to voice their opinions too loudly outside of hyper-cosmopolitan realms or to fellow academics. Articles like "The Death of God" being published in a mainstream publication like Newsweek, which would have been unthinkable a few decades ago, showed just how revolutionary the decade was.
3. Academia has a far bigger influence on the culture today than it did then. There are far more "public intellectuals" like Niel Degrasse Tyson who want to strip people's faith and lead them away from the truth of God's word. Combined with the Internet, which seems to over-reprsent academics, there's definitely a bigger influence than it had in the 1950's.
