@malwaretech I'm going to recommend a book that has explained that to me. Go get, and read, "American Nations" by Colin Woodard. You will learn more real American history (and more cultural geography) than you've ever learned in any history class you've taken.
And the answer to your question is: the values that the European colonizers of those areas brought with them still shape attitudes in those areas. People adapt to culture, and culture was already there.
