I used to believe that political correctness was just as silly as the next guy; I still do, sometimes, but, thanks to the recent campaign for President, not nearly so often. Take this example. Remember the flack Trump took when, in the third and final debate, he spoke about "bad hombres" in reference to Mexican criminals? I couldn't help but smile when, early in this book, a character refers to Doc as a "might-ee shrewd hombre." Isn't that equally problematic? Actually, no. It's one thing to appropriate a Spanish word to say something flattering about a white man, but it's another to turn someone's own language against them as an insult -- because, for one thing, it expands the insult to the entire culture, which is unfair. This PC crap is subtle, but that doesn't mean it isn't real.
