You fail to address the threat of transhumanism. And I think the suppression of the beast of prey part is the most sensible thing to be opposed to (which is not to say that it's completely sensible). For the natural high points of humanity, the great philosophers, fully partake of it.
Maybe because it is not a threat. You make it a threat by your convoluted definitions. First you say nothing is unjust, then you value this "beast of prey" thing over others. Justice can be defined with logic and reason, you don't seem to care much for that. What you've done is lower us to fighting it out instead of looking for how to cooperatively improve each other. No thanks.
