Since the evil nature is usually individualistic and the good nature is usually social, it seems odd to me that many Christians espouse the right-wing propaganda of individualism.
Absolutely. If Jesus were real, and living today, I find it utterly inconceivable that he would, for example, preach against the principle of healthcare for all, regardless of whether the sick or injured can afford to pay for it.
Could there be any greater conceit, than for someone to believe that the universe has to be simple enough for them to be able to understand it ?
