ELI5: Why are African Americans one of the most religious groups considering Christianity was essentially forced on their ancestors and used as a justification for slavery?
gpt
The message of the bible is a lot easier for the poor and downtrodden to swallow than it is the rich and wealthy.

It puts the heaviest responsibility on those with the ability to help, the rich, and tells them to share their wealth to the point of not being wealthy anymore.
If you don't care for your fellow man, you will end up like the goats in the parable of the goats and the sheep.

Whereas for a poor suffering person, "the meek shall inherit the earth".  
The bible promises that the suffering of the world will be put right in heaven, and the evil of the world will be justly judged.

So basically, it's because people made African Americans slaves and used Christianity to justify it that the message of Christianity became so popular with them.
