A motif (See, I did pay attention in English class)

So, I'm reading the United States of Walmart which is unusual for its repeated use of the word "bitch" which is probably not likely to gain it any red state readers. The blurb on the jacket states "We are all Walmart's bitches."

The Dukes v. Walmart case also featured what the witnesses politely referred to as the B-word.

And then there are Sam Walton's hunting dogs. Many of the dogs were, in fact, bitches.

So, it is kind of like a motif.

People treating other people like dogs. Women being compared to dogs. White male liberal writers playing with the B-word to get some street cred.
