Upvoted because it’s a story worth knowing, but as far as I can tell this is just further harassment/condemnation of anything pro-Palestinian. As of the end of April, independent review “finds no evidence for Israel’s claims about UNRWA and Hamas”.
Israel has declared organizations as terrorists on bad premises before. E.g. - in 2021 Defence for Children International was formally labelled a terrorist organization after they reported the rape of a 13-year-old Palestinian to the US State Department. Josh Paul, a director involved with the investigation, gives details in an interview about why he resigned from the State Dept. post-Oct. 7th. The short version is: the allegations of rape were credible, Israel was confronted, the next day Israeli forces seized all the local assets of Defence for Children International and declared them terrorists.
EU nations have formally rejected “terrorist organization” labels being applied to humanitarian/watchdog agencies in Israel/OPT before.
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.
