What makes Israel different from every other country on earth (apart, that is, from its cruel, inhuman and degrading treatment of Palestinians and other Arabs who stand up to its bullying) is that it is not a state of its citizens, but, in line with its 'Jewish state' Zionist ideology, the state of Jews all over the world - whether or not they wish to take up or refuse Israeli citizenship.
This, of course, means that while Jews get the red carpet treatment should they ever wish to avail themselves of Israeli citizenship, non-Jewish, indigenous Palestinian Arabs, whether evicted from their Palestinian homeland by Israeli forces in 1948 and 1967, or subjected to Israeli military occupation and the violence of Israeli settler thugs since 1967, haven't got a snowflake's chance in hell of ever being granted Israeli citizenship.
Yes, the Palestinian remnant, which escaped being ethnically cleansed in 1948, and which now constitutes 20% of Israel's population, are Israeli citizens, but of a distinctly inferior, second-class kind.
As it happens, one of the latter's MKs had recently dared to place a bill on the Knesset's agenda, calling for Israel "to be defined as a state of all its citizens." That is, mandating real equality between Israeli Jews and Israeli Arabs.
The result? "On June 5, the Knesset issued a press release stating that its Presidium (a group consisting of the speaker and deputy speakers) voted to disqualify [it]." (Israeli lawmakers kill 'equality of all citizens' bill before it is even introduced, Mohamed Mohamed, mondoweiss.net, 6/6/18)
Yes, Virginia, Israel is an apartheid state.
