I am not sticking up for ADL, which I agree has tilted way too far towards the defense of the Israeli government and surrendered some credibility in the process. JVP is controversial for good reason, and it is not reasonable for people to cite JVP as evidence that mainstream Jewish Americans broadly agree with a maximalist anti-Israel position. But they are not a hate group.
Right now I look at ADL the same way I look at RationalWiki. I don't trust editorialisms from RationalWiki at all. Who would? But when RationalWiki presents receipts, I look at the receipts. ADL's "editorial" voice is not very useful right now, but their specific reporting often is.
At any rate, my major point here is: Jewish Americans face unique, widespread, material safety issues. If you're operating under the impression that it's easy to be Jewish in America as it is to be Irish Catholic, do some reading and revise that opinion. From what I can see, that would be a very difficult claim to defend.
