The claim was made that there is a conflict between core beliefs between liberals/humanists/secularists and fundamentalists.

This is only true if evolution is nothing more than a core belief. If the concept of non-discrimination is nothing more than a core belief.

But neither of those concepts or others like them, are core beliefs. Evolution is not a belief like creationism is a belief. Evolution is. Creationism is a concept derived from "the word of God".

It is not an equally valid/equally invalid belief system vs. belief system. It is the way things are vs. the way someone wants to perceive things (and wants others to perceive things).
