The notion of needing skin in the game to be be concerned enough to discuss it is an odd point as well. Being human should be enough to warrant being concerned about the plight of other innocent humans on whatever side.
Everyone knows there's countless issues across the world that are harrowing and you don't need a family member directly affected to be bothered about something. For example I don't think I've ever knowingly met a Uyghur Muslim but I'm devastated reading accounts and reports from China regarding the genocide. However as I'm not personally involved it will admittedly not be something I think about for a while but I still believe I'd be allowed to share my thoughts on the matter, but from some people's POV the information I have seen would be labeled as propaganda to make the Chinese government look bad.
It makes one feel quite helpless as what can you really do apart from read about it and then discuss? It seems distasteful to block it all out but it's also not productive to read article after article or follow the threads of posters apparently in the know going back and forth (or choosing not to reply when asked uneasy questions as has happened here). I recall reading George Orwell's account of going to fight in the Spanish Civil war, a choice to risk his life in another country's conflict, it's a staggering notion, like the Brits and other nationalities that went to fight with Ukraine, I don't know if it is brave or reckless, ideally you can look back and see you were on the right side of things but so many obviously can't having given their lives for one cause or another.
Relating to the Israel Palestine conflict calls for people to educate themselves are from the right place, as I've said early on both "sides" will have their own scholars and account of events you could spend a lifetime wading through it. It's going to sound mighty ignorant but even just this thread is a lot to get through, and as usual the subject instigates people making sweeping assumptions, accusations of racism/ antisemitism. It's just mad to think that individuals are able to commit such atrocities whether it's intentionally starving civilians or gunning down attendees of a music festival.
(This post is a tad vague and broad simultaneously but in my defense this isn't an outright Israel Palestine conflict thread, it might not be a bad idea to have one)
