Dreher points out this is true of the left, but the right practiced the same thing for years.
The comments basically make the same point that both sides do this, have always done it. It’s a fear thing. Once you hook your base on existential fear based politics, you’ve got to keep it going. It’s nuts.

I’m not so sure this is a case of “both sides do it”. While the cultural wars began as a Republican power grab, they are now on to something else more fundamental: the construction of the new social order. So the war at hand is not like that of the Moral Majority (1980-95), or of the Kingmaker sequence (1996-2006), where social conservatives gained substantial control of the GOP. We are ending the third cultural war, the Fight of Southern Ascendency (this is the one that Dreher and Drum take as wrapping up). The new cultural war, the one that does matter is one about ordering of society in a world that is likely to have more social inequality, less economic, and quite likely less political freedom. Dreher is onto this battle.
Briefly, here is the shape: the New Order looks to be broadly consumerist in character — or “soma.” The nature or economically skewed society will be reifying social conditions. With less opportunity, the nature of the beast is to become defensive. So the markers of class become more important (and thus more consumer-like in orientation). Status quo arguments such as “natural aristocracy” will drop in. Theologically, the turn to Creation, and creation orders represents more of the same. Btw the Banner has been publishing this stuff with some regularity.
In a society that is heading to a greater hierarchical arrangement, the one place of resistance is that of religion,since this posits a different order (think Luke: Magnificat, Jesus’ first sermon with the text from Isaiah). In ts context, atheism is a class marker — as indeed we see it happen — but a class marker in a hierarchical setting.
So there is the real cultural war: creating a space, a possibility for transformation for communities. Against the hierarchy (plutocracy — tho it is likely to have some other name), there is the struggle for the particular, the erratic, the lumpiness that resists an ordering. The battle over Obamacare had this flavor, or at least hints at this. I think the issue is actually more complicated.
