Some random comments from what I (Cotswold dancer, and without false modesty, a bloody good one for 20 years until I retired) have read so far:

Morris will not die, the English tradition is danced all over the world;

The Morris Ring might well die, not least for their intransigence regarding women but also because any young dancers they recruit are immediately taught to dance like old men - I joined a well established Ring side when in London in 1979, the average age was about 55 and I was the youngest at 25. At practice, I was taken aside by the foreman and told that I was dancing too energetically and that "you cannot dance like that all day, you will be exhausted". I replied to the effect that yes I could dance like that all day but he and his pals probably could not.

Dancers should dance for their own enjoyment first, if they cannot enjoy it no one watching will;

Morris is neither old nor strange - all this talk of pagan ritual is bollocks. Cotswold is probably no older than late 18th or early 19th century.

All dances are made up - some made up earlier than others.

Location is irrelevant - enjoyment and performance is all.

There are very few people who care about "The Tradition" and those who make a big deal of it should be avoided.
