False dilemma, as there can always be some agreement even if there is no universal agreement. Christian morality does not differ significantly among various Christians, although doctrine and priorities often do. And right before that quote, I said: Can people twist it to justify anything they want? Yes, but people can do that with anything. This is true of the law, and especially true of atheists "making their own choices based on intuition, empathy, and experience". How are these at odds? That depends on what you think the aim of enlightenment is.
