Because you’re playing pedant with people’s lives to stroke your own ego and/or prove that you’re the smartest one in the room. Meanwhile, people make those same arguments to try to discredit anyone who says the IDF and Netanyahu are killing civilians on purpose, that they’re killing women and children with abandon, that they’re committing war crimes like they’re going for the high score.

Perhaps you don’t have malicious intent, but you should at least recognize that you sound like someone with an agenda and haven’t conveyed a take that they haven’t all made themselves before.

In short, you sound like a shill for war crimes, whether you mean to or not, and you should reflect on why you feel it’s important to quibble about the difference between “crimes against humanity” and “genocide.” This is not an international courtroom.
