But I do not do so. Religion as it is cannot be divorced from humanity as it is, any more than science as it is can be divorced from humanity as it is. To me, a religion that proposes an unworkable scheme proposes it to humans for whom it is unworkable. One can't simply blame the humans because they don't fit the idea, any more than one can blame the ideas because they don't fit the humans. Its human ideas as much as human nature. This difference in viewpoint probably stems from our different ideas about the origin of religion.
I'll buy that, but to my eye its also a limitation of the teachings. There is a lot of good in Christianity, but it is hard to see a straight line from the teachings of Jesus to the nature of multilateral trade agreements, and so forth, and yet the health and happiness of people depend on such agreements, and a lack of such agreements leads to conflict.
