Political Zionism belongs to the 19th century - out of date and backward in thinking. Ethnicity is a delusion of the mind. The moment you give someone a 'reason' to tribalise they will run with it, and the walls will start popping up soon after. Tear down the fictional walls of ethnicity in mindspace first, and true multiculturism and integration will follow.
The same case can be made that Political Islam (like that of Hamas) belongs to the 7th century. I guess this would make Political Zionism 1200 years more advanced.
