This is some amazing, and scary stuff.
The Bellamys and the pledge inspired socialists worldwide, and in the places of the socialist Wholecaust (of which the Holocaust was a part): 62 million slaughtered under the Union of Soviet Socialist Republics; 49 million slaughtered under the Peoples' Republic of China; 21 million slaughtered under the National Socialist German Workers' Party.
The Bellamys promoted a government takeover of schools, the placement of flags at the schools, and robotic chanting of the pledge to the flag with the old notorious gesture. When the government granted their wish, the government schools imposed segregation by law and taught racism as official government policy. The schools mandated the robotic chanting of the pledge with the straight-arm salute and persecuted and expelled children who would not comply, arrested parents, and even took children from parents on allegations of "unfit parenting." There were acts of violence and lynchings.
The USA still follows similar anti libertarian policies promoted by the Bellamys and by socialists in the Theosophical Society. Many socialist policies caused the USA's big, expensive, oppressive government, its aggressive military socialism, and its growing police state. It caused the Great Socialist Depression (from the Federal Reserve Act of 1913, the Smoot-Hawley Tariff Act 1930 etc) that persisted and even lasted through U.S. involvement in WWII. The Pledge still exists along with laws mandating that teachers lead the robotic chanting every day for twelve years of each child's life (though the salute was altered). The government still owns and operates schools, including the same schools that imposed segregation by law and taught racism as official government policy. That policy even outlasted the National Socialist German Workers' Party (NSGWP) by over 15 years. After segregation in government's schools ended, the Bellamy legacy caused more police-state racism of forced busing that destroyed communities and neighborhoods and deepened hostilities. Those schools still exist. Infants are given social security numbers (socialist slave numbers from 1935 during the NSGWP) that track and tax everyone for life. Government schools (socialist schools) demand the numbers for enrollment.
The pledge and the flag have become examples of how dangerous government schools are (and how dangerous government is in general). The brainwashing ritual has indoctrinated many students of government schools with the national socialist propaganda.
At any given moment, valuable information about a topic can disappear from Wikipedia simply by any neo-nazi or other hooligan deleting it from Wikipedia and substituting pro-nazi propaganda, which they try to maintain on the site. Dr. Curry's work, similar to many Wikipedia additions and improvements, has been attacked by neo-nazis repeatedly.
Some victims of goverrnment schools vandalize Wikipedia articles, not only through their sheer ignorance, but also for malicious reasons. They delete anything they do not like, even if it is true information.
