My older dog has demonstrated to me the racist reactions of much of the local citizenry as I walk her on a short leash downtown and many step back on seeing her wearing her friendly (Lab) black fur with BIG white teeth demeanor as she marches on. Pretty funny really.
Apparently the same racist folks have finally rising in the USPS seniority ranks to get the walking routes. It's really pure dog racism.
Dogs are, of course, a different species than humans, so it’s all OK.
