> used in the British Isles from 1820 to 1850 to describe young boys who tended the family or community cows

This sounds like exactly the kind of definition that would get appropriated to belittle slaves. See also simply, “boy.”

That's your own prejudice coming out. The word boy may have a negative connotation in some usages, but in this case it's referring to literal boys.

The term was used for family and community farms, not for large ranches / plantations.

The fathers and sons would tend to a small head of cattle used to feed their family and the community. They did not and could not afford to own slaves.

Plus the term was used well after Britain outlawed slavery.

I think the point being made is that it seems plausible that a term used in Britain to refer to literal boys was repurposed later in a different context to be a demeaning way to refer to an adult man working with cattle in the US.
