Mudcat consensus, which I support, is to present full data on songs, and as a result including the racially and sexually offensive material. The user may make his own changes if he uses the material.

But if you are concerned about your own audience (website and/or punlications), and what you wish to present, as well as what your audience will accept, you must decide. The decision ultimately must be based on your own beliefs if you are to live with it.
Maybe this is an individual decision that only you can make.
