Day also denounced sins against the poor. She said that "depriving the laborer" was a deadly sin, using similar language to the Epistle of James in the Bible. She also said that advertising men were sinners ("woe to that generation") because they made the poor "willing to sell [their] liberty and honor" to satisfy "paltry desires." Day was opposed to Social Security. In the "Catholic Worker," February 1945, she wrote:  Day's argument preceded the view of U.S. Supreme Court Justice Clarence Thomas, who argued that welfare emasculated African American males. In the "Catholic Worker" in May 1951, Day wrote that Marx, Lenin, and Mao Tse-Tung "were animated by the love of brother and this we must believe though their ends meant the seizure of power, and the building of mighty armies, the compulsion of concentration camps, the forced labor and torture and killing of tens of thousands, even millions." She used them as examples because she insisted that the belief that "all men are brothers" required the Catholic to find the humanity in everyone without exception. She explained that she understood the jarring impact of such an assertion:  In 1970, Day emulated Maurin when she wrote: Day encountered anarchism while studying in university. She read "The Bomb" by Frank Harris, a fictionalized biography of one of the Haymarket anarchists. She discussed anarchy and extreme poverty with Peter Kropotkin. After moving to New York, Day studied the anarchism of Emma Goldman and attended the Anarchists Ball at Webster Hall. Day was saddened by the executions of the anarchists Sacco and Vanzetti in 1927. She wrote that when they died, "All the nation mourned." As a Catholic, she felt a sense of solidarity with them, specifically "the very sense of solidarity which made me gradually understand the doctrine of the Mystical Body of Christ whereby we are all members of one another." Discussing the term "anarchism", she wrote: "We ourselves have never hesitated to use the word. Some prefer personalism. But Peter Maurin came to me with Kropotkin in one pocket and St. Francis in the other!" Dorothy Day's anarchist distributist economic views are very similar to the anarchist Proudhon's mutualist economic theory whom she was influenced by. The influence of the anarchists Proudhon and Kropotkin also led her to label herself an anarchist. Dorothy Day states: "An anarchist then as I am now, I have never used the vote that the women won by their demonstrations before the White House during that period."
