Try to make sure you’re not fighting with it. As thoughts enter your head, simply let them, then let them drift away as you very mildly try to reassert your attention on whatever focus you’ve chosen. I’ve heard it described as “observing your own thoughts”. Watch them come in, watch them go.
Honestly for a portion of the ones here online, I don’t think they actually care that much about Gaza except as a convenient tool to attack Americans. It’s academic to them. I don’t expect it’ll stop once Trump is in, they’ll just switch to criticizing Americans overall. They’re mostly leftist agitators, and I honestly think they hate moderate progressives the most, since we’re trying to improve capitalism which makes it harder to undermine and destroy.
For people that actually do care, it’s a personal, emotional argument about not being able to feel good about it, which I understand. It’s a sort of trolley problem. If they don’t vote, they kinda just walk away and the trolley runs over a bunch of people, but they don’t have to watch and bear a sense of personal responsibility at that emotional level for being a part of it. It doesn’t actually benefit Gaza, but there’s only so much they could really do anyway.
