>After all, as last two years have so amply demonstrated: people are fine with genocide.
Last two years? Try last few decades at the very least. People only care about the war in Gaza more because it's controversial. For non-controversial cases people just agree it's bad but shrug their shoulders.
In many European countries people do care about the Bosnian genocide - I mean the geographical distance is not that far from where they live.
This also explains the more prevalent ignorance concerning the other two genocides of your list: they are simply for away from the place the respective person lives.
