100% agree that factions of this country have embraced a terrifying and dangerous jingoism in recent years. It's undeniably threatening when a truck decked out in 800 American flags and bumper stickers pulls up next to you. I'll refrain from elaborating since we're on a Disney message board.
I intended to refer more to attractions with that optimistic "Great Big Beautiful Tomorrow" ethos implicitly celebrating American culture, technology, achievements. I'd argue even the classic Epcot dark rides subtly tapped into this sensibility.
Attractions like Hall of Presidents and American Adventure (and Lincoln, to a lesser extent) are more explicitly patriotic and therefore problematic; they whitewash U.S. history and have been out of step with American historical scholarship for decades. In spite of these shortcomings, I still believe they have some value and contribute a touch of intellectual depth to the WDW experience (imagine how effective they'd be if meaningfully updated/reimagined) that doesn't really exist at DLR.
But of course, it's simply personal preference. Obviously the modern Disney company will never again build an attraction like HoP, CoP, AA, Horizons, etc., so it's mostly a moot point.
