Query: author more interested in pushing his political and socials views

This author is more interested in pushing his political and socials views on unsuspecting young minds than he is in presenting a fact-filled instructional text. It is quite a shame that it is even used in any school. Do any of the class instructors actually read the text? I hope not - because that would mean that they are deliberately perpetuating dishonest education and telling students how to "feel" politically and socially.
