Metaphors aside, Liberal Christians believe they have moral superiority due to their support of social programs. They assume that the government will give more to the needy than those who give of their free will. Such assumptions reveal their low opinion for their fellow man, and gullibility to trust the government.
I also have a low opinion of people in general, when it comes to money you can't trust anyone. But I also have a low opinion of Government, recognizing its corruption and inefficiency.
I like to believe I'm cognizant of when I'm being manipulated, and resisting it is an automatic response. Perhaps this is why I'm more conservative, because more are on the left telling me what to think.
