Is anyone aware of the history of Baa baa black sheep. What it is about?
"Baa baa black sheep"
The Black sheep was the black slave.
"Have you any wool"
The goods they were to collect, be it wool, cotton and the like.
"Yes Sir yes Sir"
Was how the slave was to answer to his master.
"3 bags full"
The amount of sacks they were meant to bring at a time.
So on this occasion the use of the word black does mean black person and their enslavement. This is why some may find it offensive.
Black board. That one is just silly.
This radio clip of Stewart Lee talking about "political correctness gone mad" is interesting.
