How does "death to the IDF" mean death to the entire adult population? Regardless of mandatory service in the past, they aren't in the IDF now, and they aren't the ones "just following orders." I also don't think Bob Vylan is actually suggesting that every person in the IDF be killed, regardless of complicity, but calling for the downfall of the organization perpetuating genocide.
"Death to ICE" doesn't mean the same thing as "kill all ICE agents."
Missing the point. "Death to [organization]" is not synonymous with "kill all members of [organization]." Even if it did, my other point is that the entire country is not in the IDF. You've made claims and extrapolations that have nothing to do with anyone's actual beliefs. It wouldn't be genocide regardless.
