Very informative! I'm glad you took the time to present some background. Thank you much!
Happy to help. ;p
It's a common question here, and one I should rely just have a standard c+p job ready for. Because there is a solid answer for why, and it does make sense, if you conside the question and answer in a historical context.
Things tend to be certain ways for a reason. For example, why are Christians in the U.S. generally fiscally conservative? Whereas, in Europe and most other parts of the world, they are likely to be fiscally left wing? (Ever hear of the Christian Left, in Europe? Very socially conservative and fiscally social-democratic.) The answer has to do with free soilers in the 19th century, the rise of the socio-economic position of Evangelical Christians since the 1950s and their rise in the importance of American religious life since the early 20th century.
