I never knew about the anti-Protestant hatred until I read it on here.
I saw it as a child, the son of a Mehodist minister. I saw it throughout my last 6 years from some of my fellow students and school teachers.
Of course, what I saw was mostly anecdotal and just mocking, but in one instance my coach told me flat out that ministers were equivalent to priests, and so since I was a priest's son, I was a bastard. That's hard to forget.
