My Dad was working on a freighter out of New Orleans in the 1930s. Their route was southwest from NO to the northern coast of Venezuela (Lesser Antiles?) and then past Devil's Island around the horn of Brazil to Buenos Aires, Argentina. He saw many things. One of the things he told me about his voyages was the hate he experienced...one of his shipmates was from Galicia in Spain. He told me he had never seen hate so strong as the hatred of the Gallego. What the Gallego hated, he didn't say. Only said it was the worst he had ever seen or heard.
It probably had to do with the Spanish Civil War in some way. My Dad said the Gallego hated the Communists, most likely, but I can't remember much about it, it was long ago. I know at that time there was a civil war going on in Spain.
Dad said he had never seen such hatred in a human being...and was glad to get back to port.
