"One of the most pernicious effects of religion is that it tends to divorce morality from the reality of human and animal suffering. Religion allows people to imagine that their concerns are moral when they are not - that is, when they have nothing to do with suffering or its alleviation. Indeed, religion allows people to imageine that their concerns are moral when they highly immoral - that is, when pressing these concerns inflicts unnecessary and appalling suffering on innocient human beings. This explains why Christians like yourself expend more 'moral' energy opposing abortion than fighting genocide. It explains why you are more concerned about human embryos than about the lifesaving promise of stem-cell research, And it explains why you can preach against condom use in sub-Saharan Africa while millions die from AIDS there each year."
