Interesting discussion here. I was forming a thesis in my mind recently about Evangelicals, confessional Protestants, and Roman Catholics. There seems to be a trajectory for Evangelicals towards an increasingly Roman Catholic outlook, which seems to also translate a diminishing level of hostility towards Roman Catholics. The thesis is simple, really: by identifying themselves as Evangelicals, born again, or simply Christians, these folks are not as grounded on the Reformation. Hence they are no longer steeped in the bitterness of the Reformation.
Anyway, the Evangelicals I know seem to have shed all identification with being "Protestant" and, instead of defining themselves as being against something, are embracing the way forward as being for something else.

I do not know why he who happens to be an RC gets it but those in the camp don't. My theory is that this is what happens too, if you are Lutherite and you chuck away your vocabulary of the vestiges of "Protestantism".
