Logic and contemporary rhetoric Book

Meh. I enjoyed the first half, on formal logic and logical fallacies, but was less interested in the second, on (American) media, politics, and textbooks.

For an edition that was published in 2006, a lot of the latter type of content seemed more out of date than you'd expect in just 13 years. I know it's not the authors' fault that the media and political landscapes got so crazy so quickly, but even so. The various "political correctness gone mad" rants have dated particularly badly. Surely this:

"didn't certain Native Americans make some kind of mistake when they demonstrated during the 1995 World Series against the "demeaning symbols" used by the beloved Cleveland Indians and the Atlanta Braves?"
was already an eyebrow-raising POV in 2006? Or am I committing some kind of logical fallacy in thinking so?

There's also a section header that says "History Texts Have Gone Overboard on Multiculturalism", and some other examples of content that for me at least really detracted from the reading experience and turned it into something of a slog.
