So how did we get onto slavery in this topic? The Patriarchal system was male dominated, but it was not dictatorship, it was headship...do you even know the difference?
You have completely ignored the reasons offered about Lot and his situation to cling to your petty opinions about a man you don't even know who lived at a time and place you can't even imagine.
You want to judge him when God didn't. You want to paint him as unrighteous, when the apostle Peter called him righteous.
God says that the way you judge others is the way you will be judged yourself. Perhaps it would benefit you to think about that.
The Southern American slave owners should have known better since most claimed to be Christians. There is no justification for the kind of slavery they practiced. It was anything but Christian.
The slavery spoken about in the Bible was nothing like that. Slavery was a way to repay a debt. It provided a place to live, food and shelter whilst a man worked off his debt. There were strict laws about how to treat slave...more like hired men.
There was even a provision that if the slave loved his Master and wanted to extend his service, then the Master pierced the man's ear and he was a voluntary slave for life....does this sound anything like what took place in Southern America? You have a very warped idea about the way things were in Bible times.
