That is really a stretch. The Buddhas were large sculptures that were present for a long time and had deep religious meaning. San Francisco has a great many murals from the 20s through the 40s and often finds them in the way of remodeling or rebuilding of structures. Maybe after a few hundred years of adoration these works might compete, but as it stands they are large, misunderstood, and largely unloved. The driving need to misinterpret and destroy art is disturbing, but the history lost in this case is less than a hundred years of modest impact.
