Yes, George, the climate change concept is a religion and we know that religions are generally intolerant of opposing views.  Climate change is about worshiping mother earth.  As you point out, it is not clear that current climate is optimal.  Advantages of warming are not discussed because climate is not the real issue to the warmers.  No, climate change is about back to nature in an abstract way devoid of reality.  Those who feel closely attuned to climate change still mostly live in heated and cooled homes and drive their cars, etc. expecting other people to effect change.  The climate change crowd have always been with us but have not had a simple theme, i.e. warming, on which their mother earth worship could be centered.
