That's a well-written comment. I agree with your first paragraph. I'm actually ambivalent about humanistic hubris. I explore this further in a number of articles (links below).
I agree also that that's what conservatives say they're all about, but I take it that my political analysis cuts through much of that hype. Conservativism amounts to a surrender to bestial natural processes and hierarchies.
That's the existential choice we face: be natural and primitive or attempt to transcend our animality. Either option may end badly, but the humanist's or progressive's seems more honourable.
I'll include some links here in case you're interested. The bottom two are about conservatism.
