Serious answer: I remind myself it’s normal to be shocked by some stuff people do/create. I check the content against my ethics, and try to decide if I’m being uptight or if it really is messed up. If it’s something that isn’t unethical/harmful but I just don’t like, then I remind myself that not everyone needs to share my tastes.
If it’s genuinely terrible I allow myself to feel the anger/sorrow for a bit, try not to let it become excessive, and congratulate myself on having limits that fit my ethics. I remind myself that good people exist and they are the ones I want to support, emulate, and engage with. As others have mentioned, distraction can also help. Video games, music, socializing - whatever will move your train of thought along.
Israel has repeatedly stated their intent to continue the war in Gaza regardless of international approval. Netanyahu, among others, has stated intent to establish a long-term/permanent security presence in Gaza.
Since Oct. 7th the Israeli military has either directly killed or provided protection to lethal settler attacks in the West Bank, resulting in over 500 deaths in a section of Occupied Palestinian Territory that theoretically isn’t at war. So there’s Israeli military presence, violence, and oppression of Palestinians even where Hamas isn’t in control.
Hamas are not good guys by any stretch, but unfortunately they are the folks bargaining for Gazans. In the face of continued Israeli aggression, disregard for international approval/law, and stated plans it’s no wonder they’re demanding that any deals have rock-solid guarantees on an enforceable timetable.
