not taking sides, and not completely digested all the material above, BUT

History is not always pretty, far better from my point of view to really study it and present it to people from all sides of an issue, than pretend it never happened. This is what NOT performing these songs accomplishes: Ignorance of the past, no contradiction to blind prejudice and bias. The songs should be sung, but never with a wink and a nudge, or a shy grin, or without explaining the history and the hurt.
