I have no problem with one's believing( or not) in a personal "god" even if I think it's nonsense. The problem comes when those beliefs become clubs to beat over the non-beliver's heads. Human's need little excuse to kill,enslave, steal, etc. from one another, religion is just one more excuse and it has the side benefit of "absolving" the doer of his crime. Human's are naturally endowed with various traits, the knowledge of "good" and "evil" is not among them. Those concepts are learned, for better or worse, after birth and are not always of free will.
