Removing the negative from your first sentence (I don't care what it is "not", I only care what it "is"), I read [Consciousness is the basis of human rights because consciousness leads you to you assume, all other humans would experience the world in essentially the same way you do]. I can't completely parse this, but as I read it I don't think this is true; my assumption of human rights is independent of whether all other humans "experience the world in essentially the same way you do".
For the second part, can you give me a concrete example of an entity that doesn't "meaningfully differ from [my]self" that isn't a human so that I can weigh this properly? My point is that as of now no such entity exists so I can't give this any creedence.
