The writer had a great "narrative" of his own, until he said that. Christians believe that the Genesis accounts are monumentally germane to the problem of combating liberalism, socialism, communism, elitism, progressivism, enviro-wackoism, abortionism, multiculturalism, and the like. Christians' worldview includes the reality of original sin, God's judgment, along with His powerful, remediating mercy. Liberals deny it. So do libertarians.
Well and good to disbelieve Genesis, as is the writer's prerogative. Not so good to gratuitously include his disbelief in an essay addressed, at least in part, to his Christian-right allies in this, a greater cause: developing a uniform narrative that would appeal to voters (since they seem to value narrative so highly).
Here's your narrative, and it must be harped stridently: "Obama, Hillary, Pelosi, et al, are trying to dismantle the Constitution. They are driving us toward civil war." Maybe that would get someone's attention. We would be called mean-spirited; but guess what? We already are.
You are right. When I read the Genesis comment I almost stopped reading but I didn’t. Christians believe the Bible is the written word of God and that God has the final say so in all that happens on this earth whether liberals believe it or not. While I would like a good “sock it to them” response to some of their nonsensical beliefs, I believe the final decisions will be God’s. In the meantime, I will stand up for freedom, the Constitution, the United STATES of America and do my part to save our American way of life.
