Germany has some of the most restrictive data collection laws. And yet... Germany has a central registry of all Jews, because of the address registration and the religion tax. The last thing you would expect them to have!
Huh? My understanding is that they have religion data only for catholics/protestants, and only on local level, not in a central database. Which yes that should be killed too but no other faith is recorded, since they only collect taxes for those two.
