Modern art as communist subversion

In January 1957, a man named Arthur B. McQuern, describing himself as a retired Iowa farmer then living in "this artist town on the west coast"--Laguna Beach, California--writes to express indignation against the modern art on display there. McQuern was especially incensed by a recent exhibit, which caused him to write an essay he mailed to Congressman George A. Dondero. Here is a small portion of that essay:

"...the essence of the 'modern' doctrine apparently is to believe in nothing...The idol adopted by the modernist writers is a twentieth-century hybrid character which is made to appear as being neither good nor bad...The ultra-modernist is unconcerned with beauty and truth...By a standard of ethics peculiar to the 'moderns' truth has no stability or positive purpose but to them is only a point of view shifting and drifting with the tide of sentiment...In both literature and art a contemptible disregard for reality...."
