No, the problem is how to establish a cohesive moral-societal whole in the midst of pluralism and "multiculturalism," for the natural and historical context for a cohesive moral-societal whole is a religion/culture that permeates the society.
This sounds like problem with our multi-ethnic, multi-racial, multi-faith society. (Correct me if that is not in anyway a problem for you.) I learned we were part of a religious minority before I needed all of my fingers to display my age non-verbally. That has affected me ever since, including my strong support for religious freedoms and rejection of religious capture of the institutions of public society (especially government).
Not many people anywhere will accept that position, for although it's endearing that atheists continue to assume that their own position is widely held, empirical data shows them to be badly mistaken.
I am under no such illusion. I am aware that at most 10% of Americans adults do not believe in a god and most hold unjustified spiritual, supernatural and religious beliefs. Globally it is harder to determine given religious oppression, state religious positions and uneven surveying, though the upper limit is probably similar.
The shift is not from theism to atheism, but rather from traditional and established religions to syncretic and idiosyncratic forms of religiosity.
This is reflected by the number of people identifying their religion as "none" (close to 30% in the US). Some of them have become non-believers, some have lost the explicit christian elements of their beliefs (some have not), others haven't really changed their beliefs but no longer choose a specific religious identity.
But again, from the perspective of moral authoritativeness, the problem is a lack of cohesion. This of course includes a lack of cohesion in morality, religion, culture, politics, and a lack of cohesion or common ground between the different generations and the two sexes.
We disagree here. I think the problem is that moral authoritativeness is an illusion. I'd like our society to come to grips with that, but I doubt it will happen anytime soon. For now, I am satisfied to just inject that notion into circulation.
The interesting part is that the atheists of old realized that if the age-old societal religion were overthrown, chaos would ensue unless something were provided to take its place (e.g. Nietzsche, Feuerbach, Marx, Comte, et al.).
I've seen the trauma people suffer when they realize they can no longer justify their old religious beliefs. It is a person-by-person process that takes time. Even if I could snap my fingers and have half of believers lose faith, I wouldn't. They wouldn't be ready for it. Instead, I'd just like the normalization of non-believers in society.
The atheists of today just say, "We don't need an authoritative moral fabric!"
I don't care what these nameless atheists say. It is not what I said. Perhaps you didn't realize it. I'd like us to realize that "authoritative moral fabrics" are an illusion and deal with that.
