Israel has seen emigration double since the attacks of October 7, 2023, and the subsequent war in Gaza. While some are choosing to leave for security reasons, among those choosing exile are activists weary of war and feeling increasingly isolated amid their country's illiberal drift.
You're talking about government repression but I'm talking about antisemitism. In my city (Montreal) there have been a few arsons and bombing attacks on Jewish schools, and some more minor things (like some idiot doing seig heils at a pro Palestine protest, or some other idiot beating up a Jewish dad in front of his kids). We thankfully haven't had any casualties, and everyone that is sane is condemning these incidents, including obviously the anti-genocide movement, but the Jews are rightfully spooked. Hell, I was spooked because my kid's school was close to a Jewish school that was targeted, I can only imagine how terrified they would be.
Of course the Zionist lie that somehow opposing Israeli apartheid and genocide is "antisemitism" is hollowing out the word and making things worse and actually creating the ground for less-than-smart people to fall for antisemitic propaganda by actual hateful fuckfaces. So it's the job of the rest of us to keep up the vigilance.
Protecting Jews in the West is (a) a moral obligation towards our fellow citizens, and (b) denying Zionism it's Big Lie, thus laying the foundation for Palestinian Liberation.
