While it may well be true that some little monsters engage in renovations as an exercise in clericalism, this article is not convincing that the renovations are a front in the liturgical wars. 

The only example of a "bad" renovation  is St. Jude Church.There is no altar rail and it does not look to me as if the candles separate the sanctuary from the people. As to the marble floor, it is not stated what was replaced and it may well have been decided that marble was the most practical alternative, from the viewpoint of maintenance or otherwise.

I am inclined to think that the disagreement Mr. DeSanctis has with some other church architects/ pastors is more aesthetic than liturgical. All buildings need to be renovated periodically to maintain their structural soundness and, in doing so, it is common to modify some design elements, something certain to meet with the disapproval of some.
