AFAICT most of American politics is explainable through that prism.
For example, in 1945 while the US was helping Europe to liberate itself from the Nazis, segregation and Jim Crow laws were still in effect back home. So we have a very difficult task of trying to sort through the past and figure out what "American" qualities are good and worth keeping, and which are negative and worth throwing away.
Progress isn't inherently good, we've got this dichotomy in the US where some people are like fuck it let's just throw everything at the wall and we'll assume that's for the better vs things are pretty good so we shouldn't do anything at all. Both are tribal and not really realistic.
Compare Europe (mostly atheist) with the US (mostly religious) to discover the consequences of dismissing religion in society.

You also don't realize how a lot of church attendance in the US is mostly cultural/social. Not to mention, Europe isn't without flaw, so it's hard to "compare" anything objectively.
Echoing the person you are responding to: the OP's original point is more about the abandonment of some guiding framework for morality, not necessarily about religious institutions.
Western European morals and philosophy are no longer influenced or controlled by religious considerations. I wish I could say the same for Australia.
While Western Europe is far from perfect, it's also not a morality-free wasteland of depravation and selfishness. This is what happens if you abandon religious moral guidance: nothing.
Second, I'd argue it's way to early to conclude that abandoning religious moral guidance is a success. At most it's an (unprecedented?) experiment that so far seems to work.
Another of your arguments is about culture during a specific time, geographically particular place. It was also only relevant to certain social classes in the Roman Empire. Then you took that and compared it to Western culture of today. However, I have made no such argument!?
Please read my comment again. Those were not my arguments.
There's a lot to criticize about churches, but having lived and breathed church life until my mid-twenties, there's also a lot to admire. A lot that I would argue we have not found a good replacement for in our secular environments, which sort of pains me to admit because I'd rather not find some vaguely liberal church environment one day.
That said, I don't mourn the fact that the power of the church has waned significantly. I think church, or at least Christianity, works best in an underdog position.
Show me a temple, a Playboy mansion or a church. And I'll show you a place whose sole purpose is sexual abuse.
In Europe we've had to deconstruct organised religion not because it was so different from the Playboy Mansion, but because it was the same. A scam of power to enable sexual abuse.
When Bill Clinton had sex with a young intern the question some people had was 'why would he jepordize his career for sex with a young girl?'. Whereas the honest question would be the reverse: 'why would he have ambition to become president if he couldn't?'
The understanding of just how we are repressed by our own evolution is not making things worse -- just less hidden.
We no longer sell a 12 year to an adult for ownership/sexual-abuse/marriage in a legal contract overseen by the Church.
The world is actually a better place now. Not because everything is okidoki right now, but because the power structures of the past were not as glamorous or sinfree as you may seem to think. At the height of Christianity in the Roman empire having a little boy to abuse was the default.
Seriously, Hugh Heffner, although not very interesting isn't anywhere near the perversion of organized religion.
