In 1968, the correct term for a Thai was “gook”, not “chink”. Stupid rednecks.
My dad goes back to WW 2, Wop, Daggo, Spic where just some of the names applied to Italian’s. He was a Natural born US Citizen, his Legal Immigrant parents were Naturalized before he was born. He fought in WW 2 under Mac Arthur, didn’t speak a word of Italian. Perfect size for Airborne.
