You know, it's true what they say - ignorance is bliss. There are those who seek the truth and need justification for their beliefs and there are those who simply don't care. They believe what they believe without any evidence at all and they put it all on faith. It IS depressing sometimes, I totally get what you're saying. But wouldn't you rather know that what you believe is justified?
"The life of a man is of no greater importance to the universe than that of an oyster." - David Hume
