John Gruber’s take on this is great:

ProPublica:

“Last week, acting on a tip, we logged into Facebook’s automated ad system to see if “Jew hater” was really an ad category. We found it, but discovered that the category — with only 2,274 people in it — was too small for Facebook to allow us to buy an ad pegged only to Jew haters.”

“Facebook’s automated system suggested “Second Amendment” as an additional category that would boost our audience size to 119,000 people, presumably because its system had correlated gun enthusiasts with anti-Semites.”

One: Facebook is a morally corrupt company. They’re just bad people.

Two: as David Simon noted, “I kind of love that ‘Jew hater’ aligns cleanly with the Second Amendment demographic. The algorithms don’t lie, do they.”
