You seem to have a very stereotypical view of what it means to be a Christian. The post lumps all "Christians" together, as if they all believe the same things. Some of us for example don't believe in a literal interpretation of the Bible, others do, and others are somewhere in between. Just like some people believe in no higher power, some people believe is some sort of higher power, and others believe in a specific, named deity.
Some of us believe that we cannot begin to comprehend a being that could do something like "create a universe". We're not so arrogant as to think we have all the answers.
We can enjoy fictional entertainment for what it is, and not worry if God approves of what fictional characters are doing.
Some of us pray not for God to do anything specific, but for God's will to be done and for the strength and grace to accept it.
We may be Christians and we may feel strongly about our beliefs but we are still human, flawed and imperfect. Some of us strive to be what we think we should be, even as we know we fall terribly short.
Of course we're afraid of dying...we have people here we love and don't want to leave. No one can be certain of exactly what awaits us. We don't believe we're headed up to some pearly gates and fluffy clouds, we know that's a child's fairy tale vision of what eternal life is like. Of course not knowing is scary.
Many of us have put God to the test, some of us have even found him lacking, some of us have cursed him, and then eventually returned to him.
I could go on, but you get the gist. Your stereotypical militant atheist view of what it means to be a Christian is a caricature, and has nothing to do with what many of us think and feel.
I wonder how many self-proclaimed atheists start praying if they have a gravely ill child or their own life is at imminent risk. Again, we're all just human, flawed, none of us are really as sure of ourselves as we might think.
