Anti-Defamation League has identified the echo symbol as a new form of anti-Semitism. Used around someone's name, as in (((Bernie O'Hare))) the purpose is to alert everyone that the person inside is a dirty, no-good Jew.
I grew up in Hellertown, a community that refused to allow blacks to use the swimming pool because they smell funny in the Summer. In fifth grade, I once joked that a nun's nose was as big as a Jew's. When i grew up, racism and anti-Semitism were pretty much mainstream.
True, the nuns beat the shit out of me after I was reported by one of the girls. But I was not disciplined for making a disgusting anti-Semitic remark, but because the nun was really pissed off at being compared to a Jew.
"My nose is not as big as a Jew," she screamed as she swung away.
Maybe I should have told her to quit her "kvetching."
Someone in the local ad biz who is anti-Semitic who likes to say that to Jews. This fellow is a faux liberal who pretends to support Bernie Sanders. But at the same time, he demeans a local Jew with Yiddish terms. to alert readers that the writer is a Jew. This also plays on Lehigh Valley hate that is just beneath the surface.
"Quit your kvetching!" he'll say.
Anti-Semitism and racism are, unfortunately, a part of my background. It's under the surface, but it's still there.
