Of course it supported slavery since that was their way of harvesting crops in an agrarian society just like everywhere else in the world at time. It would have ended with the invention of the steam engine anyway and not needed to kill 500,000 whites.
Since you’re so in favor of slavery why don’t you support it in Africa...
See how silly it is to jump to conclusions not supported by a poster!
So if slavery was so bad back then why did 75% of slaves stay on their plantations 10 years after they were freed? Fact is they had a better life and better masters than they had in Africa.
So why are you not up in arms about African slave trade going on today? Shouldn’t you be stopping that rather than running around with a 150 yr old chip on your shoulder?
