A banana peel is not a big deal. The “dominant majority” should listen but need not take on board every demand for behavior adjustment. There was no wrongdoing, other than littering of a biodegradable material, by the boy concerned, not even inadvertent wrongdoing. Routine handling of fruit waste is not a race issue. Now, however and wherever you eat, or don’t eat, a banana someone can take offense?
A banana in a noose is very serious and offensive. Don’t conflate the banana peel story with that.
