There are two articles here: one is a transcript of a speech by David Grossman at a Peace rally, calling for a broad coalition against the growing extremism in Israeli politics and society.
The second one is by an Orthodox rabbi, Yuval Sherlow who seems to agree with Grossman's key points, but who argues that Grossman is turning off the Israeli public in some of his metaphors, and is thus digging himself into a deeper hole.
I personally agree with Grossman and his tone, though Sherlow is correct in arguing that it will take Israeli public support to seek a solution.
Also, old interview with a Hadash party member on why a one-state is unworkablehttp://newvoices.org/2009/02/12/0036-4/
People speaking about one bi-national state are only proving that they are totally separated from reality. Uniting within a single state a very modern society from the first world and a very poor society living in conditions of the third world is a sure recipe for an explosion of the situation in this country. At the very same time abandoning the idea of a Palestinian state is surrendering to Israel’s extremist right wing who all the time try to establish the idea of Eretz Yisrael Shlema [Greater Israel]. You can see that the extreme Arab nationalistic idea is also at the very same idea an extreme Jewish nationalistic idea. This is proof why this idea is not something more than a very imaginary illusion.
