No it’s because calling for mass death of civilians is evil and not moral. Just because Israel is commiting genocide doesn’t mean Israel deserves to be genocided again,
Technically, you're justifying the genocide committed by Israel. "We can do genocide, but you can't" ... same logic as "we can have nukes, but you can't". I think you do not realize that you ARE a supremacist.
Who exactly is a civilian in Israel? Only the local Arab population is civilian and maybe the tiny communities such as the Druze, Samaritan, and Armenian Quarter (but only those who didn't enlist in IDF). The rest, the vast majority of Jews, are literally foreign invaders, settler-colonialists with all adults bar Haredi having served in IDF.
The correct word is: "non-combatant".
When the British invaded Hind, their total population during the occupation never exceeded 62,000, among which ~30,000 were soldiers and ~30,000 non-combatants (administrators, engineers, professionals, etc); none of them qualified as civilian. That's what Israelis are.
