As I said in another thread, Jews are about Israel.
Then you're simply mistaken. FWIW, there's plenty of Jews that disapprove of what the gummint of Israel has done over the years. Then again there's plenty of Jews that really don't care a lot one way or the other as a practical matter. Maybe you think that Jews should be "about Isreal", but that's just you trying to speak for others that are quite capable of coming to conclusions and making decisions on their own.
Peace:
However, the screwing the Palestinians got is from many countries. Only one of those countries is Israel. The others? Try damned near ever Arab state in the mid-East. Keep that in perspective. The people who only note Israel as 'causing' the Palestinian difficulty likely do hate Jews to one degree or other. That is too bad for them.
Let's not leave out the Brits and other colonial powers (including the U.S.) who have made a real bollix of Arabia and Southern Asia in general. The seeds for trouble were sown a long time before the partition of Palestine. Now keep in mind that this vast area hasn't seen lots of peace and prosperity over rceent centuries regardless, and that they could have done quite a job of mucking things up all on theiur own. But, unfortunately, we helped them, and for what we contributed, now we have to take some blame.
But while we should be spreading blame around, that's no excuse for a "tu quoque" defence; where there is injustice, let's protest it, no matter where it comes from, and no matter what horrors (and there are plenty) others may have done.
