"... the vogue for Dietrich Bonhoeffer ..."?

I agree with Rick, in his posting below, that "Books & Culture" is an excellent magazine.  But I must say that the part of the review Rick quotes raises a serious question in my mind about the judgment of the reviewer.  Notice the reference to "the vogue for Dietrich Bonhoeffer".  So, was Dietrich Bonhoeffer "fashionable," for a time, among the "boomers"?  Give me a break.  We should be skeptical about the judgment--the good sense--of any informed Chistian who would (unwittingly?) suggest that Dietrich Bonhoeffer is not what he is widely regarded--and rightly so--to be:  one of the saints of the twentieth century.  Would we talk about "the vogue for Mother Teresa"?
