Men Of One Book!

What can we say about the men of one book Who never care for other points of view and Others points of view about any matter ever? Men of one book forcefully put forth their Views to be accepted by all whether it is Right or wrong and never change themselves! For, they have nothing other than what they Know and try to bring that idea to the fore Front and ear a special name for themselves! They have no supporters but cling to anyone Who says something connected with their book As a critic to try to tarnish other one's name! What can we say about such kinds of charlatans Who want to rule others by one book only ever?
