Sadly, you are correct so far as my experience with the vast majority of American Jews.
My Mom has four Jewish friends she met at bereavement group when my father died..she has known them for 15 yrs..they are all smart, educated women with good paying jobs..they all vote Democrat..when my Mom asks them about if they support Israel, they really have no comment about Israel, they care about what happens here..and they all love Obama and dislike Republicans because they think they will take away their “Right to abortion” all four of them are in their 60s, tell me, what abortions are they having LOL..but yes that is their mentality..liberalism is all they care about. I follow one of them on facebook for my Mom since my Mom does not have facebook..not ONE post about her supporting Israel, not ONE..the only time she posted anything was when Obama was here last week and she was upset that she missed seeing her “hero” told ya liberal Jews are sick
