During my lengthy discussions with liberals, I have gained insight into the different core beliefs that are the "crux" of our disagreements. The following is an example of one core belief that separates liberals from conservatives.
Liberals believe that there are no moral absolutes. Liberals beleive that it is up to each individual to come up with a "moral code" that is right for him and his situation. For example: Liberals will justify stealing food if their family is hungry.
On the other hand, myself (and most conservatives) believe that there are moral absolutes (universal spiritual principles)that are just as relevant today as they were 5000 years ago. Morality does not change through time and circumstance. Conservatives believe that it is honorable to strive toward these spiritual ideals although we are incapable of fully reaching them. However, spiritual progress, not perfection can be achieved during our lifetime..
