There’s that as well, but I’ve always found it a strange and horrifying implication that a clone’s death is more justifiable than the death of a more ‘normal’ person. I’ve even seen people online specifically saying that clones aren’t really people, so it’s okay that they are dying by the thousands.
I honestly would have just preferred it if George had given us a Republic army vs Clones, because at least then there would be no denying that this war was waged at horrible human cost, no matter how a person viewed the clones. As it is, the ‘family friendly’ marketing of droids vs clones implies that clones are less than a true person, and for me is far more ethically insidious than just admitting that war is inseparable from atrocity.
