I went ahead and read the book before I entered the class.
They make you buy it before you start school.
Anyhow, I don't know how my professor would feel about this chapter..but I'm not worried about how the authors feel because I have no direct consequence from them.
I do not go to the college in which the authors teach.

Beware - somebody on your faculty recommended that book to a textbook committee, either because he or she (note the "diverse" usage there) knows the authors (true much of the time) or because he or she doesn't see anything wrong with it. (Or, worse still, because he or she hasn't read it. That happens more than you'd like to believe).

But don't panic. You do have an antidote - FR.
