You've read far too much into that. The way is hand is position isn't a Nazi salute. The clinched fist, specifically that design, is communist.
Nazism doesn't beat communism because Nazism IS communism. Nazi is an acronym for (in English) the National Socialist German Workers Party. Stalin called himself an "international socialist". One was a national socialist and the other was an international socialist. Both wanted the same thing, power and control.
What beats communism, fascism, Nazism and socialism by lightyears is our Constitutional Republic, the Declaration of Independence, the Constitution, the Bill of Rights and the free market system. None of the others even come close. All they do is spread death, misery and slavery. Our system protects our inalienable rights, the Marxist systems destroy our inalienable rights.
It was free market capitalism and individual liberty are directly responsible for the huge advances in science, medicine and technology. Prior to the US it took 5,000 years for mankind to make similar large scale advancements that this country made in 200 years. This is what freedom allows people to accomplish.
