Perhaps those who feel it's anti-American should be reminded that a plaque on the Lander states
Here men from the planet Earth first set foot upon the Moon, July 1969 A.D. We came in peace for all mankind . This is from
https://en.wikipedia.org/wiki/Lunar_plaque which points out that the statement "We came in peace for all mankind" is derived from the 1958
National Aeronautics and Space Act's "declaration of policy and purpose": 'The Congress hereby declares that it is the policy of the United States that activities in space should be devoted to peaceful purposes for the benefit of all mankind.'
Which bit of "
all" do they not understand?
