I have always scrutinized. As a human it is our nature to scrutinize. What is odd though is that theist don't apply this practice with regards to religious beliefs.
Have you ever had to defend the simplest scientific fact to a theist, like evolution or carbon dating? The theist seem ready to scrutinize every single point. They won't do it for religion though. When arguing (because you can't debate or even hold a civil conversation with these people) with theist they always fall back on their most inane defense of a belief in a god...."you must have faith." They won't have faith that thousands of well trained scientist have independently come to the same conclusion. Instead they want to personally scrutinize every step of scientific discovery.
I am astonished at the utter hypocrisy.
