Did you also use this rationale pre-October 7th when the western world was entirely focussed on the war in Ukraine? And if so I'd be fascinated to hear what sinister reasons were behind the millions of protestors for that war because, obviously, as they weren't protesting literally every single conflict in the world they couldn't have genuinely cared about Ukrainian lives or the right for that country to exist.
It's really not as deep as you're making out, certain conflicts are more relevant and get more media coverage in certain areas. People don't have the time or the energy to protest every single conflict in the world and you can't hold that against them.
Christ he's got a fairly common injury, yeah it's unfortunate for him but this is a bit much.
