I know this horse has been whipped to death but I wanted to add that both the christians and the muslims base their belief system on a collection of works not written by either Jesus or Muhammad. The earliest Christian writing is that of Paul in 50 AD and later, Mark in 78 AD. The earliest known Islamic writing is 767 AD and Muhammad died in 632. I often wonder why believers don’t seem even a bit skeptical about the religious rumminations of their later followers. I guess that’s why they call it faith. Anyway, we’re not going to shake them from the fog of religion by railing at the written inconsistancies of their “holy” writings, but through reason. If they reject that then there’s nothing further we can do for them. All we can do is insist that their belief system doesn’t spill over into the law or effect the culture in a negative way. By that I mean ex. the degredation of women, blocking pro-choice or teaching ID in the schools among others.
