It is interesting that with most writers, you can admire and appreciate them irrespective of their particular political, religious or social views. (You don't have to be Russian Orthodox to appreciate Dostoyevsky, or a Roman Catholic Tory to appreciate Evelyn Waugh.) But all the discussion here has been about la Rand's ideas and not about her novels.
Which rather supports this Christian churchgoer ( a more accurate and less loaded description than "Christian" tout court) of left wing sympathies in his decision not to waste time reading her immensely long works.
