With Palestine and Israel, we were able to see it with our own eyes. I remember specifically watching TikToks of a teenage girl in Gaza posting about the evacuations, hearing the bombs in the background, etc. It felt "real" to us, which is a terrible way to put it, but I believe that is why the protests are much larger than other conflicts.
We, as a world, are seeing civilian life and casualties during a war in near real-time. This is something that many of us have never experienced before.
