>>Enlightenment the historic period or religious rapture ? Morality (a rather helter-skelter set of behaviours common in a certain time span, already ranging wide in the period and land masses we witnessed as "Westerners") "recast" ?
>>Intellectualism as placeholder for logical thought, scientific method or (somewhat arbitrary defined) "rational" discourse ?

I had considered terms like "Western morality" and "adult discourse" to be jargon, where jargon is intended to ease communication by encapsulating detailed explanation that would be needed otherwise. Certainly jargon fails if the terms aren't familiar enough, or if terms are picked apart to muse over individual word meaning. As an example, "Rushmore Query" fails as jargon if people pick the term apart to deduce that Rushmore is a mountain with presidents carved on it, and query has a capital Q which is a White Supremacist construct so clearly the term is a whistleblow to MAGA ferals plotting to deface the memorial with a likeness of Trump. Unfortunately that example isn't as unlikely as you might hope.

What does "Western Morality" mean as a jargon term? My point was that Proud Boys include a piece of what used to be a fairly standard academic definition which isn't the sort of extremist position you'd expect from the vitriol poured on them- unless Western ethics now are so uncool as to be offensive. Rational discourse also is a jargon term, isn't it?
