This is ontologically and empirically false. I don’t really have time for debunking this incredibly self-masturbatory screed, but holy shit you have no idea about categorisation of beings or an arguments about the wrongness of killing. (You’re not exactly talking to someone as mentally deficient as you).
The cortical organisation argument is simply cherry-picking a worse instance that satisfies the criteria of possibility of human experience. The fact that it is already a human organism is sufficient, especially since cortical organisation doesn’t grant consciousness and even if it did by definition it would fail to describe the wrongness of killing temporarily unconscious humans.
