Like you, I felt the article took a lot of short cuts.
For a more interesting view of the split, I prefer Thomas Sowell's A Conflict of Visions, over the columnist here.
Your take does less to marginalize or dehumanize the other side, always a grave mistake when applied by either side. I have to admit, I find myself in puzzlement that some very traditional, but yet profound thinking, christians seem to not see the current world climate as I do. It is far to simple and seductive to view them as less than sincere or just dupes. It is a deeper problem than that.
Haven't seen your posts before, but will watch for them in the future.
I haven't read any of Sowell's books, but have followed his newspaper columns with great interest. The Left tiptoes around him like they do around Alan Keyes.
