Clearly not in the USA when "growing slaves" was seen as preferable from buying ones fresh from Africa.
The estate born slave was conditioned into slavery. The free born were always a run away threat and more likely to rebel. And even if they didn't were more likely to malinger. In addition, less accustomed to the harsh conditions on the plantations, more likely to die or commit suicide.
So the planters encouraged the slaves to breed and those who were good at it were rewarded
So druggie castration wasn't a feature within the USA. And you know this well based on your periodic trips to Newark.
I don't think you or Ronan have US heritage so stop piggybacking off the US afro accomplishment and stick to the Guyanese Afro. Yall come from different tribes with racist blood running through your veins. Do you realize that the American Blacks hate the Caribbean Blacks and visa versa?
Now to deal with your erroneous claim, read and educate yourself
Mutilation (such as castration, or amputating ears) was a relatively common punishment during the colonial era and still used in 1830. Any punishment was permitted for runaway slaves, and many bore wounds from shotgun blasts or dog bites used by their captors.
