It won’t bother Protestants that much, since they already do not believe in any moral authority other than their own.
You set me off looking for some stats. Starting with the Wikipedia article on
religion in the US which reports that people say money is twice as important as religion and family five times as important, I look at the
reference, apparently a Russian blog

, which adds the somewhat important detail that the poll was taken straight after the 2008 financial crisis. The polling organization is called The Barna Research Group – are they respected? Their more recent general poll is
here, but what interested me more is
Six Reasons Young Christians Leave Church [all denominations], because we can kind of guess the answers:
*#1 – Churches seem overprotective – “much of their experience of Christianity feels stifling, fear-based and risk-averse”.
#2 – Teens’ and twentysomethings’ experience of Christianity is shallow - “church is boring”.
#3 – Churches come across as antagonistic to science - (23%) said they have “been turned off by the creation-versus-evolution debate.
#4 – Young Christians’ church experiences related to sexuality are often simplistic, judgmental – “Christians are struggling with how to live meaningful lives in terms of sex and sexuality”.
#5 – They wrestle with the exclusive nature of Christianity - they are “forced to choose between my faith and my friends”.
#6 – The church feels unfriendly to those who doubt - not being able “to ask my most pressing life questions in church”.*
All this is apropos of nothing, except maybe Chesterton was on the wrong wavelength.
