Sure sure, no one minded any of the racial, ethnic, religious, or sexual slurs tossed about in your youth. Everyone was perfectly happy being insulted by anyone at any time, everyone just looked at it as a joke and laughed.
Yep. Because no one was offended, it wasn't like we ran up to japanese and yelled Hey Jap! Hey Gook! This was just slang used in personal conversation. What one might call colloquialisms. There was no hate, no offense intended, it was just part of the parlance of the times.
Just yesterday I was watching a rerun of the old 1975 game show "The Match Game" where the host Gene Rayburn and all six Hollywood panelists were doing "Japanese" imitations "taking like Japs" doing the stereotypical "Jap talk" anyone would recognize as a Jap where you substitute L's for all of your R's, in regards to one of the game questions being asked.
This went on for several minutes, everyone on stage was laughing and the whole studio audience was howling. There were no boos, no tears, no one walked out or filed a lawsuit.
Because back then, people knew how to laugh at themselves. No one took things so serious. The problem isn't familiar slang being taken as a "racial slur," the problem is idiots like you making it such an issue.
