Why the unfounded fear of absolutism?

Since I have join this excellent Secular Web site and discussed many topics with my fellow atheists and agnostics (mostly in the Political Discussions Forum) I have detected a subtle but nonetheless prevalent fear for dogmatism, absolutism and fundamentalism.

I can very well understand why such fear would exist in the first place. After all life and reality has shown us to be vastly complex, knowledge never completely perfect, and always humiliating us whenever we become arrogant in our beliefs. We have learned to be skeptics and to reject religions with their obvious beliefs in the absolutes, such as God.

However I think we need to establish some baselines in our realities or else we become hopelessly confused. I propose we should be able to define well set boundaries of the absolute within the realms of our total relative existence.

Much like the physical laws of Newton can apply to our comparative existence as humans though now completely and provable fallible in the larger cosmological realm of Einstein's theory of relativity, so should we, philosophically speaking, be able to establish fundamental laws of human interaction such as politics and economics without the fear of absolutism.

For example I think Ayn Rand's seemingly dogmatic morality for objectivism has been unjustly discarded on the grounds of absolutism, despite the fact that in the relative human realm, it can very well be true and therefore practically applied.
