The act of enslavement is in fact a two way street. You have to choose to want whatever you can buy with money in order to be enslaved. It's a choice most people just don't know they are making. For many, it's also a choice that makes sense if they want to survive. Money lets you buy food, clothes, and shelter. Making a choice to be enslaved for those is clear(but still a choice). Making a choice to be enslaved beyond that is not as clear.
"The act of enslavement is in fact a two way street. Enslaved Africans had to choose to not want to be whipped and beaten by their slavemaster for attempting to run away"
When the alternative is not something a reasonable person would choose, it's common courtesy to not pretend it's an actual choice.
