The average middle-aged "Christian conservative" is such a retard that within their own life time their ideology religion was warped from defending the US worshipping Jesus to defending Israel worshiping Jews without them even noticing.
Do you really believe this? Do you think they are irrational?
People who have that much faith in an invisible deity in the sky are retards.
There are many reasons why people might be believers in God. We might disagree why people believe but they are all entitled to have fait if they are not harming other people. There have been very many intelligent Christians in history that contributed to science and philosophy.
