To quote you
It's REALLY important to know about the holocaust if you're jewish or have jewish ancestry, but arguably safer or at least more pleasant not to if you don't.
This person, a German Protestant minister, followed your advice, did he not?
good point. I totally covered every base with that one line of advice, and meant it to apply to all people in all situations.
More seriously, my advice very clearly was a subset of the more general advice: Be fucking wary of angering powerful entities. He clearly did NOT follow that advice.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
