This is not an argument, this is just a reflection of your will as a biological person. If you were an AI, you would probably argue otherwise. I'm asking for ethical arguments here.
Why should one category of consciousness have absolute power over another? What argument is there for it, that doesn't boil down to "I'm category X therefore category X is superior"?
