“Slavery is not wrong. Bad slavery is wrong.”
In my mind, owning any human is wrong. So all slavery is bad slavery.
“Many slaves in America before the civil war and after it did not want freed.”
Fear of the unknown is not a good argument against slavery.
“They knew they had it nice; food, clothing, a roof over their heads, a good master.”
They grew their own food, made their own clothes, and had limited materials to build their shelters. All the things you think they liked about slavery would not change when they were freed!
“Likewise in the Bible good slaver is condogned but not bad.”
Even the good slavery talks about letting a man go after a certain time, but you still owned his wife and children. Because you gave him the wife and owned both of them when the kids were born.
People being born into slavery is not justifiable.
