> - Netherlands, WWII: The Dutch civil registry meticulously recorded religion. It’s a major reason ~75% of Dutch Jews were killed, the highest rate in occupied Western Europe (vs ~25% in France, where records were poorer).

Records were poorer in France because René Carmille and the French resistance sabotaged the machines. Machines made by a large tech company which was a competitor to IBM.

> Who knows what kinds of ethnicities, beliefs, behaviors or personal histories will be the focus of future regimes?

Absolutely. But I do know who has that data -- big tech, and it's willing to sell it for a nominal price. No doubt that price will be higher for a deaparate government wanting to kill everyone with green eyes, but that just means a higher profit margin for facebook as they mine their shadow profiles.
