Peter,
1) "You are also ignoring the elephant in the room - this was carved out not merely for the Jews in Palestine, but for European Jews as well. A mass migration was planned (and it happened). This was not something common in history, as you state it was."
If you accept that people have a right to self-determination, they then have a state and they make the rules regarding migration/immigration to that state.
Your point being???
2) Utopia is the only state in which there is no injustice.
Every time we make a law, draw a boundary or any real or artificial distinction there are hard luck cases or those of injustice.
We would all love to see a world where it is not so - but it doesn't happen. So, one hopes that steps are taken to attempt to minimise the injustice.
3) You seem to feel that all Palestinians have been dealt this huge injustice.
I can understand that in the case of any who were forcibly removed from property or had it appropriated, but that is only a small minority on any basis that I have read - even giving credence to the more pro-Palestinian accounts.
4) You have never come to grips with the basic tenet that the Palestinians deny the Jews and Israel the right of existence.
On the other hnad you seem to feel that a minority (of Palestinians) alleged economic injustice outweighs the right to exist of the Jews.
That is an interesting view of "injustice".
5) When referring to the dispossessed you never acknowledge or have regard to the plight of Jews
a) who lost their land/possessions by being in the wrong part of partition at the relevant time;

who were dospossessed and forced to flee from the various Arab states in the Middle East over the succeeding decades- and a complete lack of compensation for those persons from the same Arab states who bleat about Palestinians (and which states benefited by expropriating property.
You might have thought that would weigh heavily on the scales of injustice.
Or is the real difficulty, that one tiny nation (geographically and demographically), actually provided succour and refuge to victims - while all the surrounding nations with far greater orders of magnitude of land and population declined to provide succour and refuge to the victims with whom they empathised?
6) "General attitude to Arabs": well, I'll take each person on his/her merits -regardless of background, race, creed or colour -or even bridge-playing (or denigrating some: card-pulling) ability!
However, if and when someone says "you don't have a right to exist", I get a little concerned and am unlikely to make of that person my best friend. Indeed a little wariness is in order: even if you're paranoid it doesn't mean they're not trying to kill you.
Fortunately, living in a nation which encourages tolerance of all, virtually any minority recognises it is just that, and unites in love of sport and general laissez faire.
I suggest your comment is - at best- unfair. At worst I could turn the tables and accuse you of anti-semitism, but I don't.
I don't know you. It would be unfair and improper to do so.
I am attempting to deal with arguments - and attempt to sway someone whom I see as making continuing emotional pleas to consider additional facts and /or premises in an attempt to convince him - or at least mitigate a perceived antipathy.
I request that you accord me the same courtesy, rather than ridicule or denigration.
7) As to partisanship: who if anyone can be totally unbiased?
We are all biased or prejudiced by our backgrounds, family inculcation and the knowledge that we have acquired and its sources.
If I watched and read "Greater Israel" propaganda thart would be no better than (pardon the pun) taking as gospel what is broadcast on Al Jazeera.
Proof of partisanship by reference to some undefined basis of the participants in a conflict (which for some is life and death) seems somewhat irrelevant. When self-interest is at stake there will always be a measure of "partisanship".
I suggested that I - as did ben Gurion- could understand or even empathise with another's feelings.
Understanding the source of their anger might help to find an answer but the mere perception of the reason for the anger is not a justification; it is an explanation.
There are undoubtedly crazies on both sides. No group is completely right but the implementation of any policy requires compromises THAT PEOPLE CAN LIVE WITH - not those that start from a premise of the complete destruction of one group.
No matter how moderate, that is the problem that any Israeli has to deal with - and I am obviously sympathetic to THAT problem.
