All art is at once surface and symbol

I dunno, dog discrimination works differently from human racism. Pitties were considered "America's Dog" during the early half of the century, and the US even personified itself as a pittie on WW1 posters. Hell, during the 70s and 80s, everybody was freaking out over dobermans and German Shepherds.

I'd slam their faces with a medical textbook, but people like ableists and racists are a special kind of delusional that wouldn't believe in life in other planets even as tripods are zapping the entire country.
