Having lived in South Texas since the 7th grade, antisemitism was not something I encountered in my social environment while growing up. That marked the heyday of All in the Family; at least as far as Jews are concerned Archie’s prejudice didn’t go beyond ethnic/religious snobbery and not-always-negative stereotypes (good with money, holiday dedicated to eating young kippers). The signature antisemitism of that decade revolved around Palestinian terrorism. The Holocaust was a subject of history lessons, and the miniseries that aired weeks before my high school graduation.
I didn’t find antisemitism in my adult social circles, either, only in news stories and news commentary – the since-forgotten politician or two whose membership in a country club not allowing Jews drew controversy, the Crown Heights riots, Jewish conspiracy tropes, more Middle Eastern terrorism, sporadic David Duke sightings, the Boycott, Divestment, Sanctions movement, the alt-right subculture, and so on. I get the impression that a lot of folks treat antisemitism as a single phenomenon and not several. The following is probably not an exhaustive list.
