This is not just a liberal problem, it is a Western problem. The "Big Tent" Republicans want to think you can hold a culture together without unalienable norms of right and wrong, often referred to as morality.
If we can't say, "That's wrong," without fearing the destruction of some hypothetical wall of separation, we're lost. Ultimately, the notions of right and wrong become based on societal choices, and those choices are informed by those who control the media and education. It's only a matter of time before the elite run the country and, eventually, ruin it.
Sure, I agree. But who's morality? Christian? Muslim? Agnosticism?
I think society has collectively agreed that morality is a fluid concept, which means that is constantly changing to suit the realities of the times that we live in. For example, you might get some pure/hardcore Catholics to say that all contraception is immoral, but if you look at the habits of most Catholics you'll see that there is plenty of contracepting going on. Not that I have a problem with Catholics or that I'm singling them out, I'm just pointing out an example.
'Big Tent Republicans' notwithstanding; the ID still is 'Liberal Elite' or now, more prominently, Leftist Elite. (In truth an oxymoron; but of course, their perception, is our reality.)
Look long enough into every major problem our Country faces today. . .including our cultural and educational decline; and you will find a Liberal 'chicken and egg'.
