Interesting observation. You might be correct. I've often wondered if there will be a breaking point when a large segment of society stands up and says, "Enough!" and instead of bloviating, something actually happens.
Read this part again:
"Society cannot exist, unless a controlling power upon the will and appetite is placed somewhere: and the less of it there is within, the more there must be without. It is ordained in the eternal constitution of things, that men of intemperate minds can not be free. Their passions forge their fetters."
-- Edmund Burke
Burke, from what I have read, had a great influence on many of the founding fathers. A republic such as ours can only exist if the people in general have a modicum of self control, which thoughtful people understand must be informed by universal religious principles.
"If men will not be governed by the Ten Commandments, they shall be governed by the ten thousand commandments." --G. K. Chesterton
Feral humans cannot control themselves, and if the society has enough of them, such anarchy will ensue that people will be begging for martial law. This isn't theory, it will happen. Unless something changes. The road we're on now inevitably leads to the ultimate in jack booted thugism.
"Does history warrant the conclusion that religion is necessary to morality -- that a natural ethic is too weak to withstand the savagery that lurks under civilization and emerges in our dreams, crimes, and wars? ... There is no significant example in history, before our time, of a society successfully maintaining moral life without the aid of religion." ---Will and Ariel Durant
"History fails to record a single precedent in which nations subject to moral decay have not passed into political and economic decline. There has been either a spiritual awakening to overcome the moral lapse, or a progressive deterioration leading to ultimate national disaster." -- General Douglas MacArthur
