Stubbornness or dogma to be more precise is a human characteristic that is not exclusive or more prevalent in 'religious people'.
The conventional wisdom of theology tells us that ethics is all to be gained from religion. Atheists are content with this and respect that. They fail to acknowledge there was any reasoning behind the ethical intentions and resort to there Utilitarianism. There is so much more to religion than ethics and crazy absurd stories. Those stories attempt to reason with questions science can not answer. Of course the Christians, the Muslims, the Buddhists, the Jewish, and Tao are not willing to change their ideas because they see their reasoning suitable for their questions.
I am not trying to push agnosticism on anyone, or self judgment. I just want you to think and question your beliefs and how you define terms such as Faith, Justice, Piety, or whatever you may overlook
