Politics was the wrong word. Putting those issues on politics makes one's positions result in consciously placing a political stance ahead of your faith...which is not what I intended.
Although there are others, I think there's pretty overwhelming evidence that humanity has two-ish primary world views. It plays out in this country as conservatives and liberals. And they are not simply contrived...they really are foundational pov's of view that are ingrained in how one see's the world. I see Christians starting from a totally aligned position...but their stances adjust based on an inherent world view. Like anyone else, we can't help it...its the way we see things. Some put things like gay marriage, porn, and/or abortion at the top of the list and others don't (or at least, that's where they put all their energy).
I think this world view led one Tennessee county to adopt a resolution asking God to bypass them when he sends his wrath due to gay marriage. Yet another Christian say 'I think the wrath of God is more inclined to fall on those people who are so condemning and judgmental'. Because these come from the same source...a world view is the only explanation for this being such a common occurance.
