I admit to bristling a bit at your suggestion that I "do some reading" on the Jewish experience in America. I like to think that I'm fairly well read on the topic. But if it wasn't clear from the previous post, I am also a (secular) Jew, married to a Jew, and come from a large, geographically spread out (and politically spread out) Jewish family. Most of my relatives are married to Jews. I've been to more family bar and bar mitzvahs than I can count, including my own. My name (and, to some extent, phenotype) leave little doubt of my background to those who might care to know. Like you, the places and I have lived and the professional environments I have worked in have brought me in contact with many more. Perhaps unlike you, shared cultural background also offers the possibility of pretty frank discussion on matters related to Jewish experience.
So while I certainly don't presume to speak for all American Jews, or most American Jews, I am operating under much more than "impressions" or "opinions." Like your neighbors, I am describing what I, and many, many besides me, are, as you say, "currently, personally, experiencing as Jewish Americans."
The point you were supporting claimed that this was an experience that "everyone who is Jewish" faced. This is a gross overstatement, and one that is without doubt being mobilized currently for political purposes. If you want to speak about a rise in antisemitic acts in the US, we could do that, provided we are operating under a shared definition. If you want to talk about the experience of suburban Jews in the Northern Midwest, I'd be happy to hear more, and compare it to what I've heard from friends and family who live there. But I was responding to your post about why anyone would question a universalizing claim about the experience of Jews in America. Please don't tell me I need to do more reading to do that.
