Sure, but the original comment said "living out" those fantasies.

Right, but the original commenter said "living out his genocidal fantasies", which means he is actively performing genocide on someone and it also implies this is something being done with active, excitement.

I'm simply asking who are these people being genocided?

I disagree with your assertion that Trump is somehow committing genocide against Palestinians while also acknowledging that the situation there is awful and I pray it ends soon.

But last I checked the Israeli-Palestinian conflict is a few thousand years older than our sitting president.
