Activities.
The Special Committee on Un-American Activities (1938-1944) wrote that "The American Association for the Advancement of Atheism is attempting to abrogate nil laws enforcing Christian morals; to stop 'bootlegging of religion in public schools'; to stop 'issuance of religious proclamations by Government officials,' such as Thanksgiving, etc.; to tax ecclesiastical property; to repeal Sunday (blue law) legislation; to tax and nationalize church property." The Junior Atheist League was founded in 1927, and enrolled students from the age of seven to seventeen.
Elizabeth Dilling in "The Red Network" wrote that "Blamegiving Day has been officially established by the Association as a day of protest against Thanksgiving services." The program for a Blamegiving event run by the American Association for the Advancement of Atheism advertised itself as “a protest against Divine negligence, to be observed each year on Thanksgiving Day, on the assumption, for the day only, that God exists.” "The New York Times" further delineates Blamesgiving Day, writing that "A protest sermon explained the purpose of Blamesgiving: 'While others are expressing their gratefulness for the good things of the past year, there can be no harm in making a similar list of things that were not so good.'
In the 1920s, Ilya Ivanovich Ivanov "submitted to the Soviet government a project for hybridizing humans and apes by means of artificial insemination" and the "American Association for the Advancement of Atheism announced its fund-raising campaign to support Ivanov's project but gave it a scandalously racist interpretation".
