Dunno about dancing--but the music, art, statues, etc.--yes, because they are precisely sensual. THAT's what I mean by understanding the human as both body and soul. The Puritans simply repeated (was it the Gnostics?---I lost my 'heresy' book..) the error which in effect stated that people are really souls 'trapped' in fallen bodies. Denies the resurrection of the dead.
Asa to your main question, the answer lies in the Vatican's term for homosexuality: a GRAVE DISORDER.
While the homos are not ALL of it, the disorder is present--and it's defined as Whom we worship. In effect, they are worshipping the world, the flesh, and ol' you-know-who.
