More from Marquart, this time on the history of liberal advocacy of tolerance in the Missouri Synod in the late 60s and early 70s:

One question...ought to be faced.  It has to do with the well-known claim of the 'moderates' that they represent brotherly tolerance, healthy 'diversity,' 'liberating unity,' and the like, as opposed to the conservatives' penchant for narrowness, division, legalistic conformity, uniformity, etc.  In actual fact, the liberal promotion of 'diversity' was more rhetoric than reality, a tactic rather than a principle.  It was resorted to in direct proportion to the liberals' loss of influence.
