The point is that there are things we value highly, beliefs we hold dear, but if they are absolutes they can trap us into behaviors that are unhealthy for us and for the other.
What I was trying to say, but more succinctly put. A lot of the time people have an absolutist mindset - they use the "should" word often - when they claim to be something which is a subset of the philosophical "relativist", such as humanist or atheist.
