Or are you saying he's ignorant of African dance and its role in liturgy? What was the point about sex? And what do you mean about all Catholics gone Protestant?
Some Protestant groups are renowned for avoiding dance, both at church (Heaven forbid) and in private! These are the guys who really do sit on the floor when the music plays. BTW, many of them disagree with the idea of having musical instruments in church ~ too distracting, interferes with prayerful introspection, not truly a spiritual sort of thing, etc. To a degree they comprise the same group who objected to drums on stage at the Grand Ol' Opry. (You are not alone, although your allies would probably never enter an RC church even on a dare).
I've simply noticed that in our threads involving dance and church we are getting a preponderance of RCs giving the sort of comments I would usually expect out of the most conservative of Protestant groups.
Maybe what's going on is you have a group in the hierarchy who are pushing dance even in the face of no apparant demand for it.
The former Coca Cola executives who pushed "New Coke" could probably give us some insight into that error.
