No, I agree it isn't alright to offend a minority, but it has to be recognised that it is impossible not to offend anyone all of the time. In the same way I know some women who think transvestism & drag is insulting to women as it mocks them, these are a minority, yet by your logic that would be enough to have them stop it.

Black-face morris to the majority is obviously not racist as is evident by the very fact that we don't have mass outrage every time a border side dances out. Consider in comparison what would happen if a minstrel group were to suddenly strike up in the streets. Ask the general person on the street what it means & they normally think it has something to do with paganism or being spooky.

I agree there are no easy answers, but to outrightly say all blacking-up in morris is offensive & that everyone should desist immediately is not a considered response either.
