@Zenos7 "slavery was abolished in despite of religion"
https://www.britannica.com/summary/Abolitionism-Key-Facts
"Despite its brutality and inhumanity, the slave system aroused little protest until the 18th century when rationalist thinkers of the
Enlightenment began to criticize it. They argued that certain rights, including liberty, belonged to all individuals.
Quaker and other evangelical religious groups also condemned slavery for its un-Christian qualities."
Yeah, Christianity has nothing to do with the abolition of slavery.
