My point being that the very idea that the extermination of humans represents some obvious objective moral principle is still just a human subjective construct.
No it isn't. Our brains that are wired for moral behavior are a result of evolution and natural selection which are just natural automatic objective processes. Those brains were not subjectively constructed by humans but are just a result of natural automatic objective processes.
What kind of an argument is this?
Are you attempting to suggest that since our brains have evolved via an objective process that every thought we have must then reflect an objective truth?
I don't think that argument is going to hold water.

Yes. Wherever or whenever biological creatures evolve brains big enough to value well-being over suffering and survival over the opposite and start living in societies there will be acts that are objectively immoral because they threaten the well-being of the society.
Your still making the same mistake. Your wrongfully assuming that since humans evolved by a natural objective process that this somehow means that their continued survival must also be objective important.
But we already know this isn't true as many naturally evolved lifeforms have already gone extinct. So it's not a property of objective reality that highly evolved lifeforms represent anything of importance.

If those dinosaurs lived in societies and had evolved brains to value survival over the opposite yes then it would be objectively immoral for a dinosaur to consciously do something threatening the well-being of that society. You seem to be obsessed with the idea that to become extinct would be somehow objectively immoral. It isn't. Becoming extinct might be a consequence of acting immorally.
What is objectively immoral is acting against the well-being and survival of the society.
Can you please demonstrate how your statement highlighted in bold red above should be seen as anything other than your own personal subjective opinion?

Now you got the point. I don't say that something would have to be objectively not good for the universe as a whole only objectively not good for the human society. The word objective still applies.
But even then you would have a hard time getting full consensus on your opinion here. Sure, you'd no doubt get a high degree of subjective consensus from most humans. However, there will always be those humans who hold that the end of the human race will result in the end of human suffering, and therefore,
in their subjective opinion the end of the human race will indeed be a "
Good Thing".
Who's to say who's subjective opinion should represent objective reality?
Is objective reality a democracy? Do humans get to vote to see which of their subjective opinions should be held up as being objective?
I don't see where your arguments are well-thought-out. You appear to be thinking that since the vast majority of humans would most likely agree with your opinion that the end of humanity would be a "
bad thing' somehow makes this an objectively "
bad thing".
I don't think this argument would hold up in serious philosophical circles.
