Agreed that there's no neutral framework in the sense I think you mean it: however that meeting goes, it has emotional consequences.

We're bouncing several scenarios around, so to avoid confusion I will label them... A is where they show up and don't announce their ontological nature, B is where they show up and take a bloody pratfall, C is where they announce their non-basic ontological nature, D is where they show up and announce they evolved via natural selection of random modification.

If I understand what you mean by "worship them as angels," I agree that, in C, most of the worshippers would likely do that. If that's not what you meant by "worship" then I might agree with your original claim; I'm not sure.

I agree that most of the people who would worship them in C would not worship them in D. If D is what you meant by "fellow creatures" then I probably agree with your original claim.
