Query: early enviro bashing

The authors (Thomas Shepard as well as Melvin Grayson) take on a number of "liberal" causes, especially environmentalism and consumer advocacy. This book (and others) set the tone for later works, using methods such as name calling (environmentalists are "irate fish-worshipers" and "professional nature lovers") and questionable science.
