I'm sure your point of view seems perfectly sensible to you just as everyone else's does to them, but my perception of your POV is that it is woven through with a certain amount of paranoia. Maybe it's just cynicism or bitterness born of personal experience. Maybe it's perfectly accurate: if anyone has a birthright of paranoia, it's someone born Jewish.
I can't say with any certainty. I'm not Jewish and so I definitely lack that particular POV, but I have and have had many Jewish friends and Jewish members of my extended family (ie in-laws and the children they have had with "blood" relations and are raising as Jewish).
I know it's a fact that there are far more "hate crimes" directed at Jews in America than any other "religious" group. In 2014 56.8% of religion based "hate crimes" were directed at Jews while 16.1% were, despite the alarms raised by the Media and the Left (redundant?) that Islamaphobia is rampant in this nation, directed at Muslims.
It's surprising, at least to me, that 6.1% were directed at Catholics. While this is a much smaller amount than what is suffered by Jews, it isn't really that far from the % directed at Muslims. One would think (again, at least I would) that from an assimilation basis, Jews are seen much more closely paired with Christians in general and Catholics in particular than Muslims. "Judeo-Christian" is thrown around all the time and yet Muslims who, it seems to me, are much more "The Other" than Jews receive less "hateful" attention than those who represent the "Judeo" portion of the "values" alloy so many declare our nation was built with.
So yes, anti-Semitism is alive and all too well in the USA, a fact that confounds and pains me, but to suggest that in the world of popular culture, Jews are "expendable." is, I think, a step too far.
Perhaps I don't understand your use of the word, and perhaps you are willing to elaborate.
I can imagine that in many places around the country there are plenty of Americans who don't have Jewish friends, but is it by choice or due to demographics? I don't know and I wonder if you think you do, and if so how?
