"The Arabs - all of them - chose the path of war" That seems highly unlikely - I would think it pretty certain that large numbers of ordinary Arabs, like ordinary people in any circumstances, were getting on with daily life and were completely out of touch and unconcerned with all this political stuff. ."All Arabs" or "All Jews" or "All Christians" or "All Hindus" - that's the language of sectarianism and racism.

Ethnic cleansing is where one ethnic population, typically in a time of conflict, has to leave their homeland, and is permanently replaced by another ethnic population. This unquestionably happened to Palestinians in the Nakba. Teribus argues that this was justified - but that would be completely beside the point, even if the arguments were incontestable, which they certainly are not. This episode of ethnic cleansing is a matter of history. There is of course a precedent for denying another terrible fact of history, and it is rightly seen as ridiculous and shameful.

I'm very sorry the way this thread has lost it's way. If it doesn't get back on track pretty soon I suggest it should be given the chop.
