My experience is not your experience. Your experience is not my experience. Can we understand each other if an effort isn't made to find common experience, like words we can both understand if you speak Hebrew and I speak Yiddish (I speak neither, btw).
Hundreds of "Rottersmans" were killed in the Holocaust. I have no idea what they felt, what they would feel now. Should I speak for them? If I have Holocaust in my blood then it is to focus on the meaning of life, how to make it better, not the color of my skin.
You are a wonderful writer with passion to spare many times over. I predict one day you're realize that the very thing you believe you know most about, Jewishness, is the thing you know the least about. Naturally, that's what I would say because I'm the one who knows nothing about it. Nothing at all.
