> It's long been a basic assumption of experts that Palestinian's higher population growth would result in them having a much larger population in Israel than Jews.

That may well be the case in future[1], but I don't think Hamas or even the considerably milder supporters of "Palestine will be free" are proposing those river and sea borders on the assumption that it will remain a predominantly Jewish state for a couple of generations. Perhaps not all of them have in mind Hamas' October approach to the demographic imbalance, but I don't think the solution they're imagining involves leadership being chosen by popular vote either.

Israel's right of course, aren't any more democratic in saying essentially the same thing (the slogan seems to have lost currency, but you'll hear them arguing tha Gaza is part of Israel and they're not saying that because they think everyone there should have a vote in the Knesset)

[1] the other problems with such predictions is that both groups have large diasporas but if votes occur along sectarian lines then only one of them controls passports, and perhaps less darkly there is the possibility that relative population growth is outpaced by younger people becoming less interested in historic conflict dynamics (which seems to be the case in Northern Ireland)
