I’m not religious in the slightest and I barely see myself as part of the Jewish nation - but I do, just barely. It is unfortunately true that anti-semitism is alive and well, and will be for the foreseeable future. Even if I don’t view myself as Jewish, some anti-semites will, and we all know where that could lead. So Israel is the only country in the world where we can know for a fact that the government (police) will protect us from anti-semitism, not to mention won’t take part in it.
Which is the chicken-and-egg problem of ethno/theostates, isn't it? If most/all of a group are isolated to one geographical location, and largely absent from the rest of the world, it becomes easier for hate to spread in that rest of the world, because nobody there has lived experience, can have that moment of "but I know Elsa/Ahmed/Luna/whoever, and they're decent person" to challenge propaganda when they hear it (and anyone who's a minority where they live has at least one story of being the cause of such a realisation). But if you're a group that lives in those little geographical pockets, it becomes that much harder to move out, because you give up your support network and move into an area of potentially hostile people.
And of course, bigots know about this and weaponise it. Speaking as a trans person and noticing the current wave of vile legislation against us in the shit parts of the US, it sure as hell feels like the objective there is to force anyone who can leave to do so, and punish those who can't, specifically to prevent a sufficient mass of trans people building up that those same deradicalising experiences can happen (hence why the use of a stereotypical trans name in above example). But in a way it's both better and worse for us, because we aren't just born into certain bloodlines or cultures, we emerge almost everywhere, so and have to fight to make the whole world queer-friendly, rather than just being able to set up somewhere in a small pocket and let the whole world slowly become most hostile to us in response.
not all of us live in countries that have any political influence over Israel, only the US holds their leash, and protesting anywhere else can't really affect that clusterfuck
plenty of awful shit is still going on around the world that needs to be fought, and that doesn't change just because a worse thing is going on in a very specific part of the world. Climate change, for example, is still happening, still an existential threat to all of humanity, and still needs public protesting to do something about.
Which, living in a country that can't help Palestine in any diplomatic way, gets a bit annoying when people are regularly protesting about that (and before that, the invasion of Ukraine), while a huge percentage of our country's electricity still comes from burning fucking coal, we still export large amount of it to the global market, our CO2 emissions per capita manage to be some of the highest in the world, and protests about that could actually do some tangible good, but are a blip in the ocean compared to foreign wars of late. I get the anger at the injustices going on right now, but it's not anger that can get anything done here
