KKKers and other racists have used an actual passage in the Bible that implies blacks are inferior to justify treating as such...
What Bible verse implies any such thing?
Littlelilac is right. Slaveowners, Klansmen, and other racists twisted Scripture to meet their needs. Here are some examples from a popular article entitled "Roots of Racism" written by a University of Georgia law professor.
Leviticus 25:44-46 relating to the buying, keeping, and inheriting of bondmen and bondmaids.
Exodus 21:2-6 relating to the slavery of poor Hebrews.
Deuteronomy 15:16-17 also relating to the slavery of poor Hebrews.
To prove that the black race was particularly intended by God to be the slaves of the white race, proslavers cite Genesis 9:26-27 relating to the curse of Canaan.
A negative argument was made that "There is nothing, not one word, in the Old Testament to condemn, but very much to establish, enforce, and regulate slavery."
Ephesians 6:5-8 exhorting servants to be obedient to their masters.
Titus 2:9-10 also exhorting servants to be obedient to their masters.
Colossians 3:22-24 requiring slaves to obey their masters justify slavery.
Again a negative argument is made that "in the catalogue of sins denounced by the Savior and His Apostles, slavery is not once mentioned;" "not one word is said by the prophets, apostles, or the holy Redeemer against slavery;" and "the Apostles admitted slaveholders and their slaves to church membership, without requiring a dissolution of the relation."
