This makes complete sense. American religion is much more influenced by frontier Restorationism or mid-century Jesusism than it is what some dead German guy nailed to a wall nearly 500 years ago. American religious movements have largely rejected denominational labels in favor of ecumenism.
Posters who want to die on the hill that “Protestant” identity is something worth protecting can go back to their established churches an ocean away
You act like Mainline Protestants have been some historic minority and oddity in America’s history, rather than a clear majority for the vast majority of it and not that much smaller than Evangelicals now … if the whackier branches of Christianity want to have their fun, go ahead, but it seems rather strange and classless to insinuate normal older churches are somehow “less American.” Frankly, it wreaks of a South-centric view.
lol, you're just perpetuating the myth that America is some uniquely *Protestant* country, a pseudo-history invented by Yankee WASPs in the 19th century to marginalize newer Irish and Italian immigrant stock. The 13 British colonies (to say nothing of Spanish Florida or French Louisiana, lol) were always pretty diverse, never monolithically Protestant settlements.
And the other history you're trying to employ as a smear against American religion isn't even right, lol. Six of the "seven sisters" of Mainline Protestantism weren't founded until the 20th century, and the only one that wasn't (the Episcopal Church, founded 1785) was the one most dominant in the South, lol.
You're the one classlessly deriding the quintessential inventions of American Christianity: evangelicalism, fundamentalism, Restorationist theology, Pentecostalism, the Holiness movement, etc. This is the shape Christianity takes when you have a settler/pioneer population living far away from established European hierarchies. You can join the bishops and cardinals of Old Europe in turning your nose up at it if you wish, but don't masquerade as the protector of legitimate "American" Christianiaty in doing so LOL
