Historically speaking, where Protestants have spread and flourished, there also freedom and democracy have as well. I'm sure you meant to mention this first, but forgot.
This is very much worth discussing, but I've got to go for now. I would also like to look at what is it that has caused a largely Protestant nation like Germany to accept Hitler, or what caused the Netherlands to endorse euthanasia, and what caused a largely Protestant nation like Denmark to allow child pornography for a period of time. I raise these examples not to discount that democracy has flourished in protestant countries, but to look at the ultimate end of that kind of democracy and how it lost its Christian way.
