...look both ways before crossing? Me too. Making informed decisions based on verifiable indisputable evidence is a strategy that works.
However, when it comes to the subject of god, this standard of evidence cannot be met. If belief were to come without negative consequences (to the individual or society), then this wouldnt be a bad thing. Unfortunately, this all to often is not the case.
That being said, if something is believed true on insufficient evidence* AND this belief causes harm, should not it be tossed away? The alternative is equivalent to crossing the road without the benefit of the senses.
*Belief in god is held on insufficient evidence and often in the face of evidence to the contrary. (Fundamentalism, literalist interpretations, Young Earth Creationism, etc)
