I'm old and I grew up around my grandparents and their friends/relatives, most of which were born around 1900-1920.

Everyone from that time period is (well, was) insanely racist. They would make David Duke blush. It's not just blacks. Irish, Italians, Puerto Ricans, Jews, Swedes, Koreans (gooks), were all subject to their hate.

Hell, I remember when National Geographic had a show on PBS and whenever there was an anthropology segment on Africa they'd show fully ass-naked Africans just walking around doing their thing and it wasn't censored or anything. Stone age blacks and South Americans weren't really considered "people" even in the 80s, so it didn't matter.
