One sometimes reaches a point with someone where they just say the same things over and over and seem to be incapable of either learning anything or of thinking outside their particular box.  They are a waste of time and all one can say is one is glad they don't have inquisitional power.

It is interesting that some people ossify like that and others don't.  I know I have opinions now I never imagined I would have even five years ago.  I think the difference is how one forms one's views (by using what one has been indoctrinated to -- "beliefs," or by using reason and evidence -- "opinions"), and whether one sees one's views as "faith" or as opinion.  Those of the first group seem to have just too much arrogance to admit they might be wrong, and cover it with "faith" to prevent such a thought.

Rereading the above paragraph a weakness in what I said needs dealing with -- how can a thinking adult be "indoctrinated" against reason?  Of course most of it is desire -- they find a view exciting or desirable or something they wish were true -- but the main reason is they become persuaded by non-rational means -- appeals to emotions such as testimonials and beautiful churches and music and patriotism and tradition and authority (the list seems endless).  There is only one valid reason to form an opinion -- evidence and its proper application.
