how is an apple and a nigger similar ? both look good hanging from a tree
Good heavens!  How could you say such a thing?
This is the truth. The slaves weren't treated properly, they should have been hanged a lot sooner.
Slavery and lynchings were a tragically violent chapter in this nation's history, and it is dreadful to make jokes about them.  Making jokes like this could lead someone to conclude that you condone this kind of violence, and that could have serious consequences.
