I agree with Penfold. From what little I've read, Morris dancing was not originally an all-male activity. There certainly were female Morris dancers in the 19th century, and the Morris tradition was kept alive by all-female groups during the world wars. Currently there are all-female and mixed groups in abundance. It sounds to me as though a few all-male groups are having internal discussions on whether to admit women; in that case, the "tradition" is of the individual group, not Morris dancing as a whole. I'd say it's up to them, unless, as Dotsie pointed out, it affects jobs or pay, or, I might add, access to good venues for dancing. It might, too - the male networks (sometimes referred to as the "good ol' boy" networks) do tend to promote the interests of their buddies against non-members which in this case would be all women. It's a natural tendency which is often unconscious. Various "blindfold tests" have proven that bias exists even when those in charge insist they are not biased.
