This Diogenes should spend some time looking for his common sense. For that he needs a lamp less than he needs a colonscope.
If I have a failure in common sense it is my persistence in attempting discussion and debate with those who prefer to snark. Perhaps you are accustomed to finding common sense in your rectum, but to the rest of us what you produce looks more like crap than wisdom.
I’m wondering where “the rest of us” are. All I see is you.
Perhaps your lamp is low on fuel. Or your vision is obstructed by matters more fecal than philosophical.
In any event, as common sense — and any number of respondents — would indicate, since space is (by treaty) the sovereign claim of no nation, the laws regarding citizenship of babies born therein would be similar, if not identical, to those regarding similar births on the high seas.
