The disgusting shill lies again, what a shocker.

Slavery remained a major institution in Russia until 1723, when Peter the Great converted the household slaves into house serfs. The government of Tsar Feodor III had formally converted Russian agricultural slaves into serfs earlier, in 1679.

Serfdom is not slavery, dumbass.

Slavery was common in the early Roman Empire and Classical Greece. It was legal in the Byzantine Empire but it was transformed significantly from the 4th century onward as slavery came to play a diminished role in the economy. Laws gradually diminished the power of slaveholders and improved the rights of slaves by restricting a master's right to abuse, prostitute, expose, and murder slaves.[1] Slavery became rare after the first half of 7th century.[2] From 11th century, semi-feudal relations largely replaced slavery.[3] Under the influence of Christianity, views of slavery shifted: by the 10th century slaves were viewed as potential citizens (the slave as a subject), rather than property or chattel (the slave as an object).[4] Slavery was also seen as "an evil contrary to nature, created by man's selfishness", although it remained legal.[5]

Regardless I don't even grant you slavery contradicts the Christian faith to begin with since it's recognized as an institution in the Bible and it's not condemned. You're just projecting your modern day liberal humanist sensibilities to Christianity:

In Paul's letters to the Ephesians, Paul motivates early Christian servants to remain loyal and obedient to their masters like they are to Christ. In Ephesians 6:5–8, Paul states "Slaves, be obedient to your human masters with fear and trembling, in sincerity of heart, as to Christ".[96] Similar statements regarding obedient slaves can be found in Colossians 3:22–24, 1 Timothy 6:1–2, and Titus 2:9–10.[97][98][99] In Col 4:1, Paul advises members of the church, who are slave masters, to "treat your slaves justly and fairly, realizing that you too have a Master in heaven."[100] Adding to Paul's advice to masters and slaves, he uses slavery as a metaphor. In Romans 1:1, Paul calls himself "a slave of Christ Jesus" and later in Romans 6:18, Paul writes "You have been set free from sin and become slaves to righteousness."[101][102] Also in Galatians, Paul writes on the nature of slavery within the kingdom of God. Galatians 3:28 states: "There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus."[103] Similar patterns of speech and understanding about slavery are found in Peter's epistles. In 1 Peter 2:18, Saint Peter writes "Slaves, be subject to your masters with all reverence, not only to those who are good and equitable but also to those who are perverse."[104] In 1 Timothy 1:10, Paul condemns the sexually immoral, abusers of themselves with mankind, liars, perjurers, those that kidnap innocents and sell them into slavery,[105] and whatever else is contrary to sound doctrine.

So yet again, you fail at your deboonking because you're not as smart as you think you are.
