I think a one state solution is unreasonable because it’d necessarily lead to a large cultural minority and I simply don’t trust Isreali voters not to continue to oppress the Muslim population.
It's not as big of a gap as you think. There are 7 million Palestinians in Palestine and Israel (not counting Jordan or Lebanon, let alone the rest of the world) compared to the same number of Jews in Israel. This is enough for either group to hold the other in check. Then we remember that not all Jews are right-wing, so in effect the people we don't want running the government will be overwhelmingly a minority).
