They're not really thinking about aesthetic values at all . . . they are simply approving what they think they OUGHT to approve to be "modern" and "up to date" and "with it."
Their focus is not on whether a particular work of art or literature is beautiful, inspiring, or even well made. They are only concerned with being approved by their friends. The besetting sin of ECUSA has always been a desire to be on the forefront of whatever "movement" is in vogue at the moment.
