No, you have not been too sheltered. There is a vocal minority of anti-Catholic bigots, but it is a tiny minority among protestants. It's just that they labor under the yoke of a kind of mental defect, an obsessive anti-Catholic fetishism.
They should be pitied and remembered in our prayers.
I don’t really know of any Prottys hereon who’d remotely qualify as ‘RC bigots.’
Some of us are more anti-Romanism generally speaking than others of us. But I wouldn’t classify even the most ardent anti-Romanism as an
obsessive anti-Roman Catholic.
Our emotions and priorities are invested elsewhere.
BTW, what clinical criteria list do is used when assessing whether someone is obsessive anything, or not?
And what training and internships furthered the learning of the proper use of such criteria?
