One of the many things that fascinates me most about Christians, especially the fundamentalist kind, is their tunnel vision. Christians can't seem to see beyond the boundaries of what they have been taught to believe. They literally possess selective hearing and sight, and no matter what may be presented to them that is contradictory to their beliefs they will not be moved.
I have often stated that faith itself is the ultimate equalizer when discussing or arguing with theists about religion. The reason for this is that faith requires absolutely no evidence whatsoever to be deemed true. Believers love to wave the faith flag when they are backed into a corner, and for the most part it works to their own satisfaction.
I can sympathize with them myself because I was very much the same when I was a theist over 16 years ago. There wasn't a man in the world or any evidence that could sway my faith, I was like a stone when it came to my belief in the biblical god. I was unbreakable, immovable, and determined to let everyone know about my beliefs and about the one I served as lord and master of my life. What we must understand as atheists is that most Christians are happy with their beliefs no matter how ridiculous or false they may be.
Many are content to bury their heads in the sand and miss all of the joy and pleasures that life can bring. Most people I know including members of my own family have referred to me as crazy for not believing in the biblical deity they choose to believe in. Many atheists are treated as outcasts by their own families who in some sick way pity them for not accepting the indoctrination that they have.
Even the most atrocious acts committed by God in the bible are explained away by theists with such stupid quips as "he is our creator and he can do what he wants" or "who are you to question God?". Yet if any living man or woman did even half of the horrible things God has done to mankind according to their book of fairy tales he/she would immediately be called a tyrant, lunatic, mass murderer, and a host of other demeaning terms.
When your mind is clouded by faith nothing else makes sense, but the nonsense you spew. Faith makes fairy tales true, through faith it is easy to believe what is known to be impossible. Jesus ascended to the heavens, Moses parted the red sea, the walls of Jericho came down with a unified trumpet blast, etc. You don't need reason to be a Christian, all you need is its opposite: faith.
