Huh! I have 23&Me too - I am 49.8% Ashkenazi Jew. Almost all of my DNA "relatives" on that site are Jewish, so I think it must be popular among the Jewish community. I have had moderate prejudice from Jewish people (not my Jewish family). Nothing compared to the genuine anti-Semitic prejudice I experienced in school or from my fiance's mother (a Phillips as in Conoco-Phillips). I wrote it up and literally cannot find it among my Medium articles any more (it's older) but my high school Vice Principal did something inexcusable to me, and I'm almost 100% positive it was due to anti-semitism. Maybe I'll re-write it ...
