Reddit mentions of In My Enemy's House

I wrote a paper on Spiegelman for some terrible war lit class I took a couple of years ago. In Metamaus, Spiegelman basically said that he assigned some of the animals basically off-the-cuff, and I think actually mentioned how he felt bad about the perceptions that resulted from making the Poles pigs. I couldn't give you a page reference, but I worked from this Google Books snippet copy so it is probably in there. Part of his logic, I believe, was to make them clearly Gentiles, a.k.a. non-kosher.

EDIT: From the TV Tropes page sans citation: "As for the Poles, Spiegelman's reasons are complicated—he's ambivalent towards Poland because of his upbringing, so he wanted an ambivalent animal; pigs are not part of the cat-mouse food chain (but cats will eat pork), and are thus neutral towards mice (though mice will eat pork too); pigs are simply not as negative in American culture (his example being Porky Pig); the Nazis called the Poles "swine," which makes pigs a logical choice, given that the Jews, who were called "vermin," are mice; the metaphor works because pigs are not exterminated like mice, but still exploited; and so forth."

EDIT EDIT: This concept didn't not appear in pop culture, at least youth culture.
