What's ridiculous is that it's even seen as controversial by some.
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.
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.
