I think GP was referring to the fact that the United States is made up of former colonies of Great Britain, but that was such a long time ago, I don't see how it matters for the moon landing.

It’s a neo-leftist international model that divides everyone into colonizer and colonized nations without particular regard for history or reality. The former are bad and powerful. The latter weak and victims.

It offers no predictions, policy prescriptions beyond railing and an infinity of excuses for justifying pretty much anything for the latter and against the former, down to subgroups within each nation.
