No, I'm genuinely unsure what you're after. That's why I asked the question. I'm not implying anything.
All I'm saying is that it's not very empathetic (to put it mildly) to say to a Jew who feels pain at what they lost in the Holocaust, "well, did you know the Slavs had it twice as bad?"
I'm not sure what histrionics you're referring to, but yeah, the holocaust really wasn't that long ago in the grand scheme of things. I'm sure lots of people still feel the pain of it in a very real, very personal way.
If you don't, great. I'm glad. But why do you feel like you need to decide what the correct level of emotion about it should be? I ask again; what are you hoping to achieve?
