The comparison your blog makes is not apt. The fundamentalist who interrupted the "God 2000" panel was mired in religious dogma, but the man who yelled "liar" on Jon Stewart's show was objecting to Barghouti's misrepresentation of history and fact.
There can't be a genuine, productive dialogue if the facts can't be acknowledged. Unfortunately Jon Stewart allowed both guests to use this show to wrongly imply that Israel denies Arab-Palestinians their justice. But the facts are: that Palestinian-Arabs in Israel have all rights of citizenship, and that Israel has tried to make peace (and has succeeded with some countries, ie. Jordan and Egypt, to the limited extent that these countries can bare) but the Arab-Palestinians in the Territories have rejected peace again and again.
There will be peace when the the struggle for the Arabs stops being about denying the Jews a state.
