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
I attend a restorationist (disciples of Christ) church and my pastor certainly has talked about Protestantism although we are a very ecumenical denomination and have nothing against Catholicism.
