If you encountered the gemutliche Germans before the war, you would have said that they love Jews too. It never changes – chazal call antisemitism a halacha. Not a societal anomaly, not something that comes and goes or is only in a minority of people. Not something a kumbaya or courses on the Holocaust, or guilt trips (literally, trips to Europe) can fix.
Halacha yaduah she’eisav soneh ea yaakov. It’s as immutable as any other halacha. They hate you. They probably don’t even know it themselves, but if there’s a gezerah, they will almost certainly sell you out. They will protect themselves with your life if not participate in the shooting squads themselves.
Halacha yaduah – it’s known, painfull6, tearfully known. You should learn it too.
