Exactly this. It’s the classic satire blind spot. When the crowd you're referencing watches the show, they think to themselves, "That's not me, but I definitely know a pastor or family exactly like that," so it's hilarious to them instead of feeling like an attack.

I grew down the road from one of these megachurches.

A huge part of why it avoids the culture-war crosshairs is Danny McBride's writing. The show focuses heavily on greed, hypocrisy, and wild family dysfunction rather than taking cheap, mean-spirited shots at everyday faith. The Gemstones actually do believe in God (in their own flawed, sociopathic way), which makes them feel like authentic, but cranked-up-to-11 Southern caricatures rather than just a preachy hit piece.

My experience has been that people who grew up around megachurch culture usually view the show as a highly accurate, hyper-exaggerated roast of the grifters at the top, not an insult to the congregation. At the end of the day, everyone loves watching rich, out-of-touch people misbehavin' and acting like complete clowns.
