The problem is they can only equate "Disguise" as Black Face!
Many teams have come to the correct conclusion in this modern age that there are other means of Disguise that will not upset portions of society.
I would calculate that at most there are less than 200 or 300 Border Morris dancers who stick to this unnecessary practice....and Why is Disguise even needed today???

All for the want of a different Disguise!!
