This is a warning for people living in a free society, a warning about the essential threat that authoritarian movements pose for a democracy grounded in the rights of individuals. And it is a horrifying portrayal of the ways in which children are indoctrinated and groomed by organized religion and parents, the ways women are reduced to serving the purposes of men primarily by reproduction.
For fundamentalists, there is a fixed Truth and it is their sacred duty to impose that fixed Truth not only on those within their belief community but everyone. I grew up in the fundamentalist South, and repeatedly was taught that to be Christian you must witness.
That sacred duty to witness, in part because media has helped promote fundamentalists as shiny happy people, has exploded into an aggressive political machine poised for national indoctrination. As the documentary explains, IBLP built a political movement as part of its mission, a mission that is inherent across the US in all sorts of fundamentalist denominations.
Imposing dogma is the goal of fundamentalism , the only goal, by any means necessary. Nothing represents that ends-justify-the-means mentality more than the idolatry around Trump among fundamentalists. Trump the person is irrelevant as long as he remains an effective mechanism for imposing their dogma. First, the separation of church and state, religious freedom, asserts that everyone has the right to embrace or reject whatever religious dogma they choose, but no one has the right to impose that dogma on others, notably not through the mechanism of government.
Therefore, the separation of church and state is a threat to the essential mandates of fundamentalism, witnessing and converting everyone to a singular way of thinking and living. Second, fundamentalism is at the core of all organized religion at varying degrees of intensity; fundamentalism also by its nature is authoritarian.
