I think Antonio is reacting to my preference of actual humans over "Humanity" and my lack of concern for "posterity," a group of non-persons that manifestly does not exist by definition.
Correction: preference for some certain humans over other humans, with a side helping of epistemic nihilism.
I fail to see the problem here.
Okay, let me rephrase it:
For the first part... if you're
okay with taking the sort of stance you do in the full knowledge that it is privileging only a subset of people, and is denigrating/erasing others, then
own that. Be honest with yourself. Say, "okay, I'm fine with throwing young people and immigrants and nonconformists and people who for various reasons are systematically denied visibility and voice in our society under the bus! I'm a reactionary! I stand up for the entrenched and the privileged." But don't be a hypocrite. Don't try and claim the high ground.
For the second part... you can say that you don't care about "posterity" or "future generations", but at some point (protip: we're already at that point) these repercussions are likely to happen within the lifetime of people who are already alive. Some of them could very well happen while
we are alive! At that point, if you still say that you don't care, then you're not just pooh-poohing "nonpersons", you're pooh-poohing stuff like
causality and
evidence. And, well, if you're doing that, then once again I have to ask how you're able to function in the real world.
