“Low-hanging fruit”? That’s funny. The nature of morality, the alleged existence of souls, abortion (which I’ve expanded on here), and Hell (and Hell’s innkeeper, Satan): all of these items are central to Christianity (while the inane of idea of “holy” water is central to Catholicism).
Science and religion do contradict each. You might want to read Faith vs Fact: Why Science and Religion are Incompatible by Jerry Coyne.
Yes, I have successfully challenged Christianity. If what I raised was low-hanging fruit and therefore easily ripped from the tree, you would have done so point by point. You did not. Thank you for reading.
