You think terrorists need genetic data to find some Jews to target?? That's certainly not the low hanging fruit ... sounds like an urban myth to me.
Endogamy was also historically common in the Jewish diaspora before the Contemporary Period, so on average they will probably see a lot more distantly related people via 23andMe which creates an exponential increase in the amount of data scraped per user account.
You know, I hadn’t considered that as a consequence of endogamy! You’re totally right.
> Terrorists are buying the data on the black market to get a list of Jews to target, because being Jewish is something that shows up in your genetics.
As cute as the implication I just read several of the articles and see no specific evidence about the terrorist groups, just the leak. I'll finish the last one but that's a weak association if I've ever seen one.
