I agree with you.
But having learnt of this phenomenon, I remember my teacher emphasising empathy. Like some of the younger members being rather naive. Just seeing it as an edgy joke not to be taken seriously.
Others “hedging their bets” in a sense trying to appease the local power in an effort of self preservation. Which I won’t judge them for.
Another aspect to consider was the historical incident of antisemitism. Whether overt or merely “a benign joke told for ages beforehand.”
Which is incidentally why a lot of modern movements want to call out even culturally accepted forms of (what they perceive) as negative racial/prejudiced stereotypes. Because people become numb to them and that can be true.
What is not accepted now was seen as benign in the past, right? So it is implicitly allowed by the culture. That’s not to say the culture was inherently bad, merely passive. But passivity can lead to a Hitler.
I understand you perfectly.
I have understood many things reading Primo Levi's works like If this is a man.
