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
