@InfraBlue,
What you are saying is basically the way I used to think about the whole world; i.e. why can't all national borders be dissolved and everyone's liberty to migrate anywhere respected and honored?
The problem with that is that people don't honor each other's liberty, rights, and otherwise avoid harming and exploiting each other. So it puts those of us who want a world of people to be able to behave themselves well enough to deserve liberty in a precarious position.
So when people are demonstrating their will to violence by sending fire bombs and other attacks, how could you possible trust that granting full citizenship rights won't just move the subversive movement closer to home and make it more difficult to police?
Think of it another way: if the US civil war had resulted in dividing the US into north and south, and people on the losing side were vehemently bitter at their former enemies and seeking to subvert them, would you as a person on the winning side want to extend citizenship to people who might use it to restart the war from within?
Really, I am all for democracy and freedom, but doesn't democracy have to precede freedom; i.e. don't people have to first prove that they can engage in good-faith non-violent civil discourse before you can fully trust and honor their liberty? It is of course something different when you actively deny people the chance to prove themselves because you ultimately want an excuse to discriminate against them and that's not what I'm talking about. I'm talking about legitimately seeking to reach peaceful democratic relations so that you can indeed live in a free democratic society where rights and liberty, including that of migration and economic self-determination are universal. In fact, isn't that what zionism is ultimately all about?
