My guess is that the confusion comes from the overwhelming number of Baptists of convenience in Birmingham.(they're Baptists because everyone else is and the church has nice activities)

This is Birmingham, Alabama. There was previously not a lot of mixing Baptists with Protestants and/or Catholic traditions.
Baptists aren't pretestants. Protestants resulted from the Reformation; Baptists preceded the Reformation. (Real Baptists don't "do" Ash Wednesday.)
