Morris is no more an indulgent recreational hobby than any other form of dance.

Not so. Other dance forms are replete with genuine folklore - be it disco, break-dancing, Latin, ball-room, line-dancing etc. etc. Morris is the only one that claims to be folkloric, quasi-mystical, fraught with wonky history even unto menacing overtones of pre-Christian pagan ritual, but is, in fact, a wholesale post-modern revivalist fantasy dating back no further than the 1960s whatever traditional precedents might be cited.
