Why? The most common reason given for population decline is the debt crisis: people cannot afford children. However, a temporary economic disturbance cannot explain the long-term trend. There are a number of other reasons but the underlying one is that increasingly marriage and family formation is discincentivised in our society and culture.

That story, put simply, is the retreat of Christianity in the West and the emergence of a new religious faith in its place -- a new paganism. What comes amid the decline of the Christian faith is not some live-and-let-live secular liberal utopia, not a rational and atheistic political order with neutral public spaces and a culture of tolerance. Instead, we have a new form of paganism with its own moral precepts, obligations, and rites.

PRRI found that the number of those who describe themselves as "nothing in particular" has held steady since 2013, but those who identify as atheists have doubled (from 2% to 4%) and those who say they're agnostic has more than doubled (from 2% to 5%).

This study looks at which faith traditions those unaffiliated people are coming from.

Within a matter of mere decades, marriage was redefined and humanity's most basic institution was "expanded" to include same-sex couples. Simultaneously, there were demands that homosexuals be given full recognition and liberation as well. That revolution took a bit longer to gain traction, but then it gained momentum and expanded its aims. The modern LGBTQ movement represents two great achievements of the liberationists.
