As a Jew whenever you see someone self describe as a JAP prepare to hear the most insane self absorbed privileged idiocy spouted at you until you simply give up.
no joke, I am assuming what the censored term was, because the only time I heard it aloud was from a boomer like 20+ years ago abbreviating "Jewish American Princess".
I remember going to Seder with my ex and her secular family. They were having relatives from New York come visit and I was warned in advance about "the jay aye pee cousins" that would be coming and thought, "wow that sounds offensively judgemental. This should be interesting."
Then they arrived and it was like poorly written characters from a TV show had materialised in the dining room complaining about service on the private jet over and how gross our country was. Highly entertaining.
