...when you get hold of a Yankee, drive it home to him; tell him his country is disgraced; wound his pride; tell him his pure institutions are a grand sham; send him home thoroughly ashamed of the black blot on his country's escutcheon. In steamboat, or railroad, or wherever you are, hunt up a Yankee and speak to him faithfully; there is no other man so sensitive as to what others think of him.This is actually from an anti-slavery speech Brown gave in 1852. The disgrace was slavery, which would endure another dozen years. But in these times, it has a contemporary ring, except maybe for the sensitive part..
