I sang Oh Susannah in elementary school, and never even heard of the "coon" words until I was in college. The same goes for My Old Kentucky Home and several others. They are still in popular culture because they were well-wrought tunes, not because they denigrated a race, and that's the reason I will continue to play and sing them. Any other hidden agenda that is suggested as to why I want to piss off black people has likely been created in mind the mind of the suggestor.
