I think I am a Zionist, but my real opinion is something like 'it is good/praiseworthy/morally right/legitimate for [people] to build a homeland of some sort [far away from where they're currently stuck]', and I think the case of the Jews and Palestine is one example of a broader phenomenon.
Even as someone a couple of generations removed from the passage to the United States - Italian and German Catholic, not Jewish - this resonates with me.
Three out of my four grandparents knew enough about the lives their parents had left just a few years before having children to make all of this clear. And the much higher quality of life in the United States was not just because it was a wealthier, freer, and safer place to live. It was also because they lived in neighborhoods full of similar immigrants, many of them family, who worked together to build ladders into business, politics, and every other institution that didn't outright exclude them.
Any rhetoric that implies that there's something illegitimate about this is unconscionable to me. It's an implied threat to my own right to exist, and that of anyone else descended from similar immigrants, as far as I'm concerned.
