Here is a scanned copy of a real copy of Freemason Leo XIII's Encyclical Humanum Genus from 1884. Scanned authentic copies surpass internet versions in terms of credibility so you don't have to rely on an internet "transcription" or "translation" which may have been altered. Notice in Leo XIII's argument against Albert Pike, creator of the Ku Klux Klan (whose enemies included both Catholics and Black People) that he quotes from the Jewish Psalms of David as proof of his arguments. Remember, the war he is conducting is to promote heretical lord worship in the process of writing about less important topics. Remember that it is the Lord heresy that is the Gates of Hell.
Remember also that the year was 1884, 107 years after the Sacraments were changed at the Congregation of Rites when Rosicrucian Cardinals outnumbered and, by Divine rules, voted to change the Sacramental form in Latin from the Holy Ghost who is to the "Spirit who is coming." The Papacy was in Masonic hands in 1884, as the usurped Chair of St. Peter continued its mission of quietly strengthening their ranks for Vatican II, slowly removing any resisting non-Masonic Cardinals and Bishops from power. This is why the Apparitions at Fatima happened, to save the devout who could no longer rely on the Church.
