By 1842, Joseph was saying:

"…it makes my blood boil within me to reflect upon the injustice, cruelty, and oppression of the rulers of the people. When will these things cease to be, and the Constitution and the laws again bear rule?" (History of the Church, 4:544).

While preparing his platform for his 1844 presidential campaign, Joseph stated:

“My cogitations, like Daniel's have for a long time troubled me, when I viewed the condition of men throughout the world, and more especially in this boasted realm, where the Declaration of Independence ‘holds these truths to be self-evident, that all men are created equal; that they are endowed by their Creator with certain unalienable rights; that among these are life, liberty, and the pursuit of happiness;’ but at the same time some two or three millions of people are held as slaves for life, because the spirit in them is covered with a darker skin than ours.” (History of the Church, Vol.6, Ch.8, p.197 - p.198)
