Morally or legally? If morally, I'd wonder at your implied leveling of morality between the KKK, a group that seeks to enslave all that are not white and that has a history of cold-blooded murder and torture, to a group that wishes to free folks that have been attacked and persecuted because of their own natures.
I am not an attorney, but I believe the mythical African-American baker would have to supply the KKK, but would that group wish to support that particular ownership? I doubt it!
